Feature to group tabs

Hi Team

Im currently working on a rather big project, with the stakeholdes wanting more and more different repports. As of new i have about 30 tabs + 10 costum tooltip tabs. 

The bottom horizontal scroll bar is suboptimal for this amount of tabs, and i would love the idea of grouping them together, and then toggle the groups when needed.

So i fx. could put all of my tooltips in one group, and only show them when needed.

Hope the idea is well recieved
