Combine vertical and horizontal tab groups

I love tab groups… so much as they tend to fill my entire width.

So was looking into vertical.. but sadly that makes it more confusing.. so i have this idea about combing them.

Imagine you have the tab group vertically. But when you click on a group it pops to the top and looks similar to horizontal with just one group

When you add a new tab, that isnt added to group, just like today, but you can move it into the tab just like today, the only difference is, if you want to move it into a tabgroup, you have to active it first.

Hope it makes sense…
