I’ve used it before when trying out IDEs. Its really good, its a no bullshit solution to VS code. If you’ve used sublime text, Kate is similar to that as in it starts off quite minimal. On a spectrum of minimalisim and memory consumption, you have emacs, Vi, VIM at the lower end of the curve. This is for users to customize or to use the smallest memory footprint, than in the median its kdevelop/Kate sublime, and VS codium, and on the far end of spectrum you have your bloat software VS code and ItelliJ idea. Personally I’m using Vim for my projects in C, C++, Python, octave, and sh scripts I like to keep my memory footprint small which is why I use it. I have used amd’s Vitis IDE for embedded systems (which is just a fork of VS codium).
