Reduce the length of the text on the tabs such that it always fits within the shape of the tabs.

In the attached Plastic SCM 6.0 screenshot, you can see tabs with names such as:

"Items in workspace Freed..."
"Pending changes in works..."
"Branches from repositorie..."
"Branch Explorer for re..."
"Cloud repositories"

If these had shorter names, which exactly matched the button names, I would be able to mentally identify the tabs quicker:

"Items"
"Pending changes"
"Branches"
"Branch Explorer"
"Cloud Repositories"

The long tooltips with all the details are still useful.
