allow no titlebar in tabbed mode

[bgkillas]

i just want the option to have no titlebar and just use keybinds to switch between them and cant see reason to not give the option

I don't think this is the way to do this. Check out the tabbed container rendering function:
https://github.com/swaywm/sway/blob/master/sway/desktop/render.c#L776

If you want no titlebars in tabbed mode, I think the solution is to add a config option for ignoring them and then add a check for that option in the function I linked above.

This is a niche feature not in i3, and features not in i3 are generally not being accepted.

@sweenu #7350 is not about tabbed mode.

@sweenu #7350 is not about tabbed mode.

It doesn't seem to be, at least it doesn't say so directly, but AFAIK the workaround they mention (setting font-size to 0) was only needed to remove titlebars in tabbed mode, not the "normal" ones. So I think that issue is actually about tabbed mode.
