Issue Type: Bug

After last update, the repository names are not shown properly in the source control panel, the name of the branch (right) overlaps the name of the repository (left) and the panel has to be extended to see the complete name. I think that the repository name should overlap the branch name so you can see the repo you are working on it at first sight.
