It's used only to list and open your recent files. You can hide the section in Settings ■ Make it yours ・Choose how your tabs are laid out in ⚙️ Settings: a detailed list, app-style tiles with names, or icon-only circles, small or extra small, so even a huge pile of tabs fits on one screen. Hover over a tab to see which one it is ・7 color themes, light and dark. The octopus dresses up a little differently in each one 😎 ・English / Japanese (in ⚙️ Settings) ・A friendly octopus who comments on how many tabs you have — and gets bored, dozes off, or welcomes you back 🐙 ■ Privacy Tabumaru works entirely inside your browser. It does not collect, send, or sell any data. Screenshot previews never leave your device. Snoozed tabs and the list of tabs closed automatically (title, URL and time, up to 50) are saved only on your device, and you can clear them at any time. Shortcut: Alt+Shift+L opens the panel, and pressing it again closes it (the toolbar icon works the same way). You can change the key from ⚙️ Settings. You can also right-click a page or the toolbar icon and choose "Open Tabumaru". The side panel can be shown on the left or right from Chrome's settings ("Side panel position").
