in all ine one mode I can't close the last "tab"

[nk]

[12:38:02 πμ] nkour: hey 
[12:38:10 πμ] nkour: excellent work on the "all in one" window and the rest patch
[12:38:26 πμ] nkour: there is still an issue though. last "tab" cannot be closed (as it's no longer a tab)
[12:39:38 πμ] nicfit: yea, I could see that... not sure how to fix.  it needs to be fixed I suppose but here is why I never really noticed.  I have always show tabs=True and always use CTRL+W to close tabs (hide tab close button == False)
[12:39:40 πμ] nicfit: 
[12:39:53 πμ] nicfit: CTRL+w should work, right?
[12:40:05 πμ] nicfit: but I agree, that is not intuitive 
[12:40:16 πμ] nkour: ctrl+w yes
[12:40:20 πμ] nkour: or even /close if in MUC but ...
[12:40:37 πμ] nkour: hey at least we don't default to that. maybe we could default to "always show tabs"
[12:40:40 πμ] nkour: not sure
[12:41:02 πμ] nkour: I really like all in one. maybe we could have it as "you want this or that" in a first time wizard
[12:41:24 πμ] nkour: with some screenshots. if that all in one was to become massively used, then always show tab should be true or find another way
[12:41:29 πμ] nicfit: yea, maybe force always show tabs in one-window mode?
[12:41:43 πμ] nkour: yes atm that's the best /me thinks
[12:42:20 πμ] nicfit: ok, I'm a bit busy right now... feel like adding a ticket?
[12:42:30 πμ] nicfit: maybe some others will chime in with a good fix
[12:42:47 πμ] nicfit: if not, I'll try and remember to add a ticket... to get some discussion going
[12:43:01 πμ] nkour: I'll add a ticket. no worries

(In [9309]) always show tabs in one_window mode so that we can close latest tab in GUI. fixes #3720
