Don't close about:treestyletab-group tab for single tab group without other tabs

[Infocatcher]

I want ability to leave about:treestyletab-group tab in following case:

[about:treestyletab-group]
    [Child tab #1]
    [Child tab #2]

(no other tabs around)
E.g. I opened some bookmarks folder "as a New Tree" and then close initial tab (to get structure described above). And about:treestyletab-group automatically closes.

So I prefer to automatically close only about:treestyletab-group tabs without child tabs.

Hmm... I probably provide poor description, sorry.

Start Firefox or open new window:

[Initial tab]

Then open any bookmarks folder (I'm use middle-click on bookmarks folder) "as a New Tree":

[Initial tab]
[about:treestyletab-group]
    [Child tab #1]
    [Child tab #2]

Then close "Initial tab" ("about:treestyletab-group" tab will be automatically closed):

[Child tab #1]
[Child tab #2]

And I want to see

[about:treestyletab-group]
    [Child tab #1]
    [Child tab #2]

I'm use browser.tabs.closeWindowWithLastTab = false, so I don't need extensions.treestyletab.autoRemoveNeedlessGroupTab.lastTab, but I found it useful. :)

Oh, sorry, I misunderstood the initial comment!

It is a feature introduced by the commit c419a3f. Because I think group tabs are just temporary, I decided to clean up needless groups automatically. However, people who use group tabs to manage tree manually can stressed by it. So now I'm planning to add another secret preference to disable this "automatic cleanup" feature.

Instead, I've introduced the concept "temporary group tab" and "permanent group tab". Now TST closes needless group tabs only when it is marked as "temporary". I think this is better than new customizability around the autoremove behaviour. How about this?

Not bad. I'm not annoying with auto-closing of dummy tabs without children (remove last child tab => automatically close dummy parent tab), but it's easy to close them manually.
But I also prefer to have an option for temporary=false by default.

And why about:treestyletab-group?title=...;temporary=true and not about:treestyletab-group?title=...&temporary=true? Second looks more standard.

Now you can change the default behaviour. See: dec4d77

I misunderstood the spec...

Great, thanks!

Interesting, I never (very-very rare?) see ; in links on web pages.
