When I want to create a new branch on a file that has existing branches, I always end up clicking on the “<#> branches” button in the top toolbar, only to be reminded that you can’t create a new branch from the Branches modal that opens up. This is a small issue, but a bit annoying every time.
The little arrow to open the popover that does include the “Create branch…” option has a frustratingly tiny click target, and that’s at least partially why I don’t think to click it / don’t want to click it.
