SheetsGroups — sheetsmenu

Group your Google Sheets tabs into hover dropdown menus. Assign any tab to a named group: the tab bar stays clean, and hovering a grouped tab reveals all its siblings in a floating menu. No sidebars. No fancy giant folder-like tree. No new UI panels. It lives entirely inside the tab bar you already use. SheetsGroups does not send any data anywhere. No analytics, no network requests… and no hidden costs, subscriptions, fees, unlockakables. Everyone’s happy!

Features
• Hover dropdowns: grouped tabs show a floating menu on hover; click any entry to navigate
• Group customization: each group has its own color, icon, and icon size
• Reorder within groups: drag the order of tabs inside a dropdown with ▲▼ arrows
• Rename groups: double-click a group name in the dropdown to rename it inline
• Batch assign: Ctrl+click multiple tabs in Sheets, then click ▾ on any of them to assign all at once
• Quick assign: hover any tab and click the small▾ to assign or reassign it to a group
• Bulk assign: select one sheet or multiple sheets, go for it!
• Export / Import: back up your groups, colors, and icons to a JSON file and restore them anytime
• Cross-browser: It’s the same extension in Firefox, Chrome, Brave, Edge, and Opera

How to use
Assigning tabs to a group
1. Hover any sheet tab, you’ll notice a small ▾ button appears
2. Click ▾ to open the assign dialog
3.Type a group name (or pick one from Quick Assign if you’ve already created a group) and click Save

The tab now shows a small colored icon in its top-right corner. Hovering it opens the dropdown with all tabs in that group.

Batch assigning
1. Ctrl+click to select multiple tabs
2. Click ▾ on any selected tab
3. The dialog shows "Assign group for X tabs" and assign them all at once

Renaming a group
Double-click the group name at the top of any hover dropdown. Edit inline and press Enter to confirm. Moving the mouse away discards the change.

Reordering tabs within a group
Hover a dropdown: ▲ ▼ arrows appear on each row. Click them to move that tab up or down within the group.

Customizing a group (color, icon, size)
Open the assign dialog for any tab in the group. Use the › toggle to open the icon picker, and the Size and Color panels on the right. Changes apply live to all tabs in that group.

Managing groups from the popup
Click the SheetsGroups icon in your browser toolbar to open the popup. From here you can:
• See all groups and their member tabs
• Remove individual tabs from a group
• Delete an entire group
• Use Bulk assign to assign any sheet to any group by name
• Export your configuration to a .json backup file
• Import a backup to restore all groups, colors, and icons
• Clear all to remove every group from the current spreadsheet

==========================================
Would you rather your Sheets act more like nested drop down menus?
I've got you covered!

SheetsMenu
https://addons.mozilla.org/en-US/firefox/addon/sheetsmenu/
Drag Google Sheets tabs onto each other to create nested hover menus for quick multi-level navigation. The extension only accesses the Sheets tab bar to display navigation menus. It does not read, store, or transmit any spreadsheet data.
