You can do "idea diff file1 file1" to open a popup with their diff tool.

Funnily that's the one feature I dislike in IntelliJ and thus relies on another GUI

Otherwise I like having everything in one place: code, containers, databases, remotes...

And I hate it with a passion. The fact they they introduced their own terminology, their own lifecycle, always makes me doubt what will happen when I use any feature of their client.

Magit OTOH stays much closer to the true git. Although for anything slightly more esoteric I still prefer native git cli.
