Photoshop does a lot of things in really stupid, convoluted ways. Krita also does a lot of the same things in equally stupid, convoluted ways, but different than PS so you get no benefit from knowing how its done in other software. Text editing comes to mind. Both PS and Krita feel like they were designed by drunk people when it comes to doing anything beyond writing text and picking a font/color/size.
Nothing concrete from what I can tell. Becoming a hard fork is relatively recent though (mid-November of last year, roughly).
As a side note, I understand why Gitea and Forgejo went for a “copy GitHub Actions” approach to their CI, but man do I wish more self-hosted repo software tried to copy Drone/Woodpecker instead. Iterative containers in the pipeline is such a smoother build experience, and it kind of sucks that Gitness is the only one doing it (that I know of).
They were still pulling in mainline Gitea changes while introducing their own stuff last I checked.
Depends on the features.
Git has some counterintuitive commands for some commands you may want to do when you want to quickly do something. Being able to click a button and have the IDE remember the syntax for you is nice.
Some IDEs have extra non-native Git features like have inlined “git blame” outputs as you edit (easily see a commit message per-line, see who changed what, etc.), better diff/merge tooling (JetBrain’s merge tool comes to mind), being able to revert parts of the file instead of the whole file, etc.
I’m going to be honest, I don’t really like VS Code’s Git integration either. I find it clunky and opinionated with shitty opinions.
