What do you think about creating a Sprite Tabs group?

Features

Sometimes, I often work with a lot of sprite tabs on.
Many tabs cause a lot of time to find out what tabs are when I work.
So, I think we need the feature to group a lot of tabs. Like Frames Group, Layers Group.
Could you please consider this idea I suggested?

there is already something similar. not really groups, but it might help:
