Filtering of git branches in the selector

[unpunnyfuns]

Is your feature request related to a problem? Please describe.
When switching branches, there is no way to filter branches. On large git repos this can create a prohibitively large list to select from.

Describe the solution you'd like
A way to filter branch names in the git branch selector, similar to the token value selector.
