My mistake on the wording, I should have said "mediocre", perhaps. I can't edit the comment now, oops sorry.

I am referring to lack of an installer, and also the default shortcuts which clash with the distro, and in general I've seen features come to Linux a lot later. So a better way to put it is that Linux feels like an afterthought to Jetbrains. I do follow and also raise issues you on YouTrack but find they often languish.

Their IDEs are still overall pretty good, but I gravitate towards VS Code now.
