Ability to name tabs from the config file

[stratosgear]

After looking around (and consulting in the discord channel) it seems there is no way to name your tabs from the config file (you can only name them manually, from a running instance).

I think there ought to be a way to do that from the config file, too!

Thank you for taking the time writing down this issue.

For anyone that wants to pick this up:
I think it would only make sense to have them be named in the layout file, as opposed to the config file for now.

Yes, I meant the layout file (sorry for messing up the terminology)

Hey guys, since I recently made a PR for tab-bar, my mind is still fresh on this and I have some questions.

Will control characters be allowed in the tab name from layout file? And can we prevent that easily? Currently an unescaped \n or \t will completely mess up the spacing count and rendering, but I don't know if we care at all, it's deliberate bad input and it doesn't result in a panic, just a bad result from bad input.

And since any kind of characters will be allowed into tab name I guess we should probably change the width count from chars().count() to unicode-width. I can make a PR for that.

Thanks for raising these issues!
I am all for the tab width pr.
I am not too sure about the escaping one. Maybe open an issue? At some point templating for configured strings make sense maybe. So we can keep that for collecting ideas.
