Feature request: Specify a list of tabs to retain on switch

[ahernsean]

I am frequently using Git Graph, which shows a graphical tree of all of the branches and commits. I would like to be able to specify to Restore Git Branch Tabs (RGBT) that it should not close a tab called "Git Graph" when it switches. I'm imagining a list of strings for RGBT to check against before it closes any tab. Ideally, the strings could be patterns to match.
