I have heard people complain about the staging concept (personally I find it useful, because you can do 'git add -p' which allows you to craft intermediate commits or to-be-squashed fixup commits after you've finished some development), so it's removal in this tool is unsurprising. And it is nice to auto-stash on branch change (though personally I think that they should've made stashing a much better-supported concept in their Git wrapper -- I've never really liked how stashing was implemented in Git).
I do really like that they appear to have worked hard to remove all of the super-scary warnings that Git likes to spit out. As someone who has taught high-school students how to use Git (among other things), I've learned that the easiest way to scare away people from your project is to have bright-red warnings in response to a user doing something. Most students describe it as though the computer is effectively screaming at them. Some tools over-compensate for this is and spew emoji in response to user input, so I'm happy this tool has struck the right balance.
