Please implement grouping and middle-click close functionality

[neurodiverseEsoteric]

It's the only two essential features that all the other "sidebar/vertical" tabs addons have, that Sidetabs doesn't, which is torture considering that this is the only addon that actually works and offers all the other essential features (like scrollable pinned tabs) ...

Middle-click close has been added. (Finally)
How do you think grouping should work?

[neurodiverseEsoteric]

Thanks, but middle-click also activates scrolling. Was thinking grouping would be more like a subtree-style thing for tabs opened from another tab, but I'm not fully committed to that idea yet...

By "activates scrolling", do you mean that the Windows scroll "compass" shows up? There might be a fix for this. I'll have to find a mouse and test it.

I never really liked the subtree thing that other extensions do. I couldn't see the benefit in tracking which tabs opened which other tabs, and it always just made it look more disorganised in my opinion. I'm definitely open to adding some form of grouping, but I probably won't take the subtree approach. (It's just not for me, so I probably won't want to work on it)

Fixed the "Scroll compass" bug on Windows in 0.61

I figured since this issue is already talking about grouping -- multi-select would be a nice option too, either ctrl+click to add individual ones, or shift-click to do a range. I like this mostly for being able to close multiple tabs simultaneously, move them all into a new window or such (another feature that would be very useful); though it would probably be a prerequisite for grouping too.

How do you think grouping should work?

Not OP but to answer your question, at least like it does in Edge? I know some of the other sidebar tab add-ons will allow multiple layers or tiers, but something like Edge's functionality is a good place to start.
