It would be really handy to be abble to manage groups of tabs like in some "projects groups".
It would allow on left navigation panel to create/select "groups" and it would display a set of tabs (like last openned in this group).

We are managing tens of projects and have often several repo for each. At this time we're only abble to see first character of each tab name and have to scroll most of the time.

At least several rows of tabs would be a first step of improvement :)
