Switch repository tabs based on recency like in ST

[FichteFoll]

Problem description & Preferred solution

When switching repository tabs, I'd like them to switch like tabs do in ST: based on which tabs I used previously (based on a stack that can be cycled by holding down the ctrl key).

Alternatives

Make this configurable because editing key bindings in SM is kind of cumbersome due to having to extract the default bindings manually.

+1, I basically stopped using Ctrl-Tab completely in SM because without MRU option it just doesn't make a lot of sense because it's hard to predict where you'll end up.
