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".
