tab-bar-mode support

[isamert]

I saw that it's mentioned in the README but I would like to know if there is any progress or what do you have in your mind generally. I would also like to contribute for getting this feature if you can give me a few starting points.

Cool!

I was actually thinking about that last night, and I think the way Bufler handles tab-bar-mode makes a lot of sense (look at bufler-workspace-tabs.el):

• make a separate minor mode for it, persp-tabs-mode or another good name — that way it's opt-in for people who (1) don't want it, or (2) use an older version of Emacs
• advise tab-bar-* functions as needed with :override (not sure how many you need to treat that way; also, please use the new advice system — Perspective uses the old system in several places, but there's no reason to do so for a brand-new feature which relies on Emacs 27 anyway)
• it feels like it shouldn't be a ton of new code to get working (I haven't studied tab-bar-mode very closely, so not sure about that side of it, but Perspective itself has plenty of helper functions), so I think it can all fit in the current perspective.el source file

I'm pressed for time right now, so by all means give it a try if you want! It's great to have more people familiar with the Perspective code.

Hey, I have been using the snippet of code from this comment for a few weeks successfully: Bad-ptr/persp-mode.el#122 (comment).

@LemonBreezes: That code wouldn't work directly in Perspective, which has different hooks and parameter setting from persp-mode. Did you adapt it? If so, please post the changes you made. I'd like to give it a try.
