Chrome Side Panel Tips & Tricks: Top Picks

The best way to use Chrome’s side panel is to treat it as a customizable workspace, not a fixed sidebar. Our top pick is to master the built-in side panel’s reading list and bookmarks, because it requires no extensions and works across all devices. For power users, the Sidepanel API-driven extensions like Sidepanel Notes or Mercury Reader offer deeper functionality, but the core tips below apply to every setup.

What to Look For

Before diving into specific options, understand what actually matters when using the side panel:

• Accessibility: How quickly can you open the panel? Keyboard shortcuts and a consistent icon beat digging through menus.
• Contextual awareness: Does the panel change based on the tab you’re viewing? A good side panel shows relevant info (like your bookmarks for that site) rather than a static list.
• Customization: Can you resize it, pin it, or change its width? A rigid panel that takes up half your screen is worse than no panel.
• Performance: Does it slow down page loading? Heavy extensions that run in the background will eat memory.
• Sync: Does your panel data (reading list, notes) sync across devices? If not, it’s only useful on one machine.
• Integration: Does it work with Chrome’s built-in features like bookmarks, history, or reading mode?

1. Built-in Reading List & Bookmarks Panel

Chrome’s native side panel (click the side panel icon in the toolbar, or press Ctrl+Shift+B on Windows/Linux or Cmd+Shift+B on Mac) gives you instant access to your bookmarks and reading list. It’s the most reliable, zero-cost option.

Strengths: No extra downloads, syncs with your Google account, and loads instantly. The reading list lets you save pages for later with one click, and it shows a clean list that you can check off.

Trade-offs: Limited to basic lists—no notes, no folders for reading list, and no filtering. You can’t resize it beyond a fixed width.

Who it suits: Casual users who want a simple way to save articles and access bookmarks without cluttering the toolbar.

2. Sidepanel Notes (Extension)

If you take notes while browsing, this extension adds a persistent notes pane to the side panel. It saves automatically and can be opened with a shortcut.

Strengths: Lets you jot down ideas without switching tabs. Notes are stored locally and synced via Chrome sync if you enable it. You can format text with markdown.

Trade-offs: Requires an extension, which means a small performance hit and potential privacy concerns (read the permissions). The free version has limited storage; premium adds cloud sync.

Who it suits: Researchers, students, and anyone who frequently needs to copy snippets or write thoughts while browsing.

3. Mercury Reader

Mercury Reader is a popular extension that cleans up articles for distraction-free reading. Its side panel mode shows a simplified version of the current page.

Strengths: Removes ads, clutter, and formatting issues. It also lets you adjust font size and theme. The side panel view is great for reading while keeping the original page accessible.

Trade-offs: It doesn’t work on all sites (e.g., dynamic web apps). The side panel is separate from the main reading view, so you have to toggle between them.

Who it suits: People who read long-form articles online and want a clean, focused layout without losing the ability to refer back to the original.

4. Custom Side Panel via Chrome Flags

For tech-savvy users, Chrome’s experimental flags allow you to enable a side panel that shows your bookmarks, history, and reading list together. Go to chrome://flags, search for “side panel,â€� and enable the “Side panelâ€� flag (or “Unified side panelâ€� in newer versions).

Strengths: Gives you a unified panel with tabs for bookmarks, history, and reading list. It’s native, so no extension overhead.

Trade-offs: Flags are experimental and may change or break. The layout can be buggy, and it might not work on stable builds.

Who it suits: Early adopters who want the latest features and are comfortable with minor instability.

5. Sidepanel API Extensions (e.g., Sidepanel Google Keep)

Extensions built with the Sidepanel API (like Google Keep’s official extension) integrate deeply with the side panel. They open a dedicated panel that can be resized and pinned.

Strengths: They are designed specifically for the side panel, so they feel native. Google Keep lets you take notes, capture screenshots, and set reminders—all without leaving your current tab.

Trade-offs: Requires a Google account and the extension. Some features (like offline access) may be limited. The panel can be slow to load if you have many notes.

Who it suits: Heavy Google Workspace users who want seamless integration between browsing and note-taking.

6. The “Pin� and “Resize� Trick

This isn’t a product but a technique: right-click on the side panel’s header and choose “Pinâ€� to keep it open across tabs. You can also drag the edge of the panel to resize it, making it as narrow or wide as you like.

Strengths: Works with any side panel content—built-in or extensions. Pinning saves you from re-opening it constantly.

Trade-offs: A pinned panel takes up screen space permanently. If you have a small monitor, this can be annoying.

Who it suits: Multi-taskers who need constant access to a reference list or notes.

How to Choose

Budget: All the options above are free (except some premium features in extensions). If you’re on a strict budget, stick with the built-in reading list—it costs nothing and does 80% of what most people need.

Use case: Ask yourself what you’ll use the panel for. If it’s just saving articles for later, the built-in reading list is perfect. If you need to take notes, get an extension like Sidepanel Notes. If you want a clean reading experience, Mercury Reader is better. If you live in Google’s ecosystem, Google Keep’s side panel is a no-brainer.

Common trade-offs: The biggest trade-off is between simplicity and power. Native features are fast and reliable but limited. Extensions add functionality but consume memory and may raise privacy concerns (always check permissions). Also, consider sync: if you switch devices often, ensure your chosen method syncs via Chrome or an account.

Frequently Asked Questions

How do I open the side panel in Chrome?

Click the side panel icon (a rectangle with a vertical line) in the toolbar, or use the shortcut Ctrl+Shift+B (Windows/Linux) or Cmd+Shift+B (Mac). If you don’t see the icon, right-click the toolbar and select “Side panel.â€�

Can I use the side panel on mobile?

No, the side panel is a desktop feature. On mobile, you can access bookmarks and reading list via the menu, but it’s not a persistent panel.

Why is my side panel not showing?

Make sure you’re on the latest Chrome version. Go to chrome://settings/help and update. Also, disable any extensions that might interfere, or reset Chrome flags to default.

Does the side panel slow down my browser?

Native features don’t. Extensions can, especially if they run background scripts. Check Chrome’s task manager (Shift+Esc) to see memory usage.

Can I add custom links to the side panel?

Yes, you can add bookmarks to the bookmarks bar, which appears in the side panel. Some extensions also let you add custom shortcuts.

Is there a way to make the side panel transparent?

Not natively. Some extensions or themes might offer transparency, but it’s not a standard feature.

Bottom Line

Start with Chrome’s built-in reading list and bookmarks panel—it’s free, fast, and syncs everywhere. If you find yourself needing notes or a cleaner reading view, add an extension like Sidepanel Notes or Mercury Reader. For the most integrated experience, use Google Keep’s side panel. Avoid experimental flags unless you’re comfortable with occasional bugs. The key is to experiment with what you have first, then add only what you truly need.
