Comment 10 for bug 71303

+1 with additions.

Add a branch status called "Vintage" for those "Mature" branches that you don't want to see all the time.

Initially the branch view will show all branches except those with a status of "Merged", "Abandoned" or "Vintage".

A drop down list has the following selections:
   - Current
   - All
   - New
   - Experimental
   - Development
   - Mature
   - Vintage
   - Merged
   - Abandoned

Where "Current" is the initial selection (and default) selection.
