Groupbar position config please.

[LemonKronos]

I think it would be cool to be able to change the position of the groupbar. Right now it can only be at the top of the group, but for me and a lot of people who have waybar at the top of the screen, it might be quite cluttered. It would be nicer if we could position it at the bottom or even side way - which could be great if the group have a lot of windows . Thank!
