Yep. I cannot deal with "oh we decided to 'innovate' so we moved all the options to different places, renamed them and also half of them regressed" on a daily basis. I changed the IDE like 6 times in my career and I refuse to do it again. And when IntelliJ released "Rust Rover" that didn't have "attach to process" functional, I decided "I need to finish my own thing before current one regresses to the point I can't use it".
I still have 25-30 years of work ahead of me until I retire (I hope), so I am not going to invest in something that can just go and disappear. That's why I GPLed this one, so everybody is sure I'm not gonna rug pull the code into something commercial.
Also, I think the UX nowadays is not great, and I wanted to see "how hard it's to make something better". Long answer: not that hard, just expensive. But not impossible.
