I've had 7000 tabs open as well (currently 3700, I backup the session file and start again every half year or so). What I think would be handy would be if tabs would be auto-grouped by domain name, and that I could define domain groups (like work, newspapers, computing sites, youtube, etc.).

You can do that with Sidebery, at least partially.

I see manually managed groups in Sidebery but nothing automatic... it doesn't look like you can move more than one tab into a group at a time, or even move a single tab into a specific group without manually dragging through a huge scrolling list to find it.

Look into the Panels feature, it has auto-move by URL regex.

I'm not seeing anything like what you describe... can you tell me exactly where that feature is located?

Right-click on the panel, choose "Configure panel", in the resulting overlay there's a "Move tabs to this panel", click "Manage rules".
