Have they got rid of the treeview of repos? That was a vital feature. I never used the tabs because they didn't all fit on screen, and the tab UI doesn't allow you to distinguish between different repos with the same name. Ironically they seem to have adopted what I considered the worst feature of Git Kraken. Oh, and it let you see all your repos' status (what branches are checked out) at a glance. This is such a pai…
ST dev for Windows here. How many repo do you typically work with at once? Would it help to show the "ahead/behind" indications in the tab headers?
Personally, I have a 2560x1440 monitor and I keep ST on it fullscreen. I usually have ~7 repos open but sometimes need to open up to 15. I can fit 11 tabs but look at how much wasted space is in each tab: https://www.screencast.com/t/vKrSNe5APy
On the older version of ST, like 1.5 or something, the tabs were only as big as the name of the repo so each tab was much smaller. This worked great.
Alternatively, make the tabs just add extra rows so instead of having a scrolling list, the tab bar grows vertically instead.
