Git/Stash list of UX problems

Task: Add a new repository. A git repo on stash.a.c with a custom branch.

This has many problems...

I have a reference repo that I am copying. It claims it is a "Git" repo as the Source Repository field. BUG1: It should report "stash master on stash.a.c"

When not knowing this, selecting Git and filling in the appropriate fields then clicking save, apparently has no affect. BUG2: Validation errors not visible but are hidden in the advanced disclosure. BUG3: No visual clue is given that the operation failed. BUG4: Navigating to another location in the UI does not warn that config will be lost(I did this and had to start again).

On finally checking the Source Repository drop-down and figuring out that it was a shared repository...BUG5: Config of shared repos is only available to admin users(which luckily I am one).

BUG6: It should be possible to override fields of a shared repo. In particular the branch.

I'm suggesting the UX could be improved here somewhat.
