SheetsMenu от sheetsmenu

Nest your Google Sheets tabs into each other to create cascading hover menus. Drag any tab onto another and it becomes a child: the tab bar stays clean, and hovering the parent reveals all its children in a floating menu. Children can have children, the nesting goes as deep as you need. No sidebars. No fancy giant folder-like tree. No new UI panels. It lives entirely inside the tab bar you already use.
SheetsMenu does not send any data anywhere. No analytics, no network requests… and no hidden costs, subscriptions, fees, or unlockables. Everyone's happy!

Features
• Drag to nest: hover any tab to reveal the ⤵ handle, drag it onto any other tab to nest it as a child
• Cascading menus: children that have their own children show a ▶ arrow, so hover to open the next level
• Active trail: the full path from root to your active tab stays highlighted so you never lose your place
• Batch nest: shift+click / ctrl+click multiple tabs using Google's native selection, then drag any of them to nest them all at once
• Reorder children: ↑ ↓ arrows appear on hover inside any dropdown to move tabs up or down
• Unnest: click ❌ on any child row to remove it from the nest
• Rename in place: right-click any child in the dropdown to rename it inline, it’ll update the actual sheet tab and all nest references
• Drag into dropdowns: while dragging, simply hover a parent to open its menu and drop directly onto a child row for deep nesting
• Hover over a header, tap on ⟲ to sort the group
• Export / Import: back up your entire nest structure to a JSON file and restore it anytime
• Cross-browser: works in Firefox, Chrome, Brave, Edge, and Opera

How to use

Nesting a tab
• Hover any sheet tab and a small ⤵ handle appears
• Click and drag the ⤵ onto any other tab
• The dragged tab disappears from the tab bar and becomes a child of the target
• Hovering the parent now opens a floating menu showing all its children.

Nesting multiple tabs at once
• Shift+click/Ctrl+Click to select multiple tabs using Google's native tab selection
• Drag the ⤵ handle on any of the selected tabs

Deep nesting
• While dragging, hover a parent tab for half a second to open its dropdown, then drop onto any child row inside it. The dragged tab becomes a child of that child.

Renaming a nested tab
• Right-click any row in a dropdown menu. An inline input appears pre-filled with the current name. Type the new name and press Enter and the actual sheet tab is renamed and all nest references update automatically.

Reordering children
• Hover any dropdown row: ↑ ↓ arrows appear. Click to move that tab up or down within its parent.

Unnesting a tab
Hover any dropdown row and click ❌ to remove it from the nest. It reappears in the tab bar.

Sorting a group
Hover over the menu's header and a small ⟲ appears. Click on it to sort that current menu
