Panorama "move tab to group" event?

[The Wanderer]

I'm trying to update BarTab so that the "select nearest loaded tab" option works
as expected in post-3.x versions of Firefox. This mainly means making it work as
expected with Panorama.

I've already gotten most of it working, but I still get unexpected behavior when
moving the current tab to a different tab group, via the tab context menu's
"Move to Group" sub-menu. In order to correct that, I need to be able to respond
when such a move happens.

BarTab responds to tab closings by listening on the TabClose event, via
tabContainer.AddEventListener(). The obvious thing to do would be to add another
listener, with an appropriate event; however, looking at the MDN "Mozilla event
reference" page, I do not see any apparent event which seems like it would fire
on "tab move to group".

(Based on what I've learned about the apparent underlying implementation of tab
groups, I suspect that "move tab to new group" is currently implemented simply
as "move tab to new offset in the current window's tab list", which - in the
absence of tab groups - doesn't seem like that the sort of thing that would need
an event. That would explain the lack, but it doesn't really help me even if
true.)

How can I hook in to respond when a tab is moved to a new tab group?

Every time you let somebody set a limit they start moving it.

Anyone?

Is there a better place to ask this question? I'm not sure it would be welcome
on the main Firefox development (list|group), but that's the only other
candidate I know of, unless there's an appropriate IRC channel somewhere.

Where do the Panorama developers and/or maintainers hang out?

I'm developing an extension named Pano [1] which shows all tabs in tabgroups to the sidebar.

In my case:
I also searched the DOM event which is dispatched when a tab moved to another group, but could not find out.
So, I decided overwriting `TabView._window.GroupItems.moveTabToGroupItem()` method [2] for dispatching a DOM event "TabGroupMove"

Thanks; that's a bit beyond my previous experience and skill level, but it looks
like I might be able to adapt that approach into something which could work.
