When a tracked branch is removed from the remote there’s currently no way to quickly see that it was deleted. The graph will show if it’s been merged but other than that some external tool is needed.

git branch -v will mark it as [gone]:
* develop c5ce1fb5c Merge pull request #1099 from ...
feature/abc c5ce1fb5c [gone] Merge pull request #1099 from ...
feature/xyz c5ce1fb5c Merge pull request #1099 from ...
