One thing I wish JetBrains would explore is building a fully native NON-JRE text editor that is a direct competitor to Sublime Text, but has a rich plugin API. I would love to see their take on a Sublime like editor. Atom and VS Code were the only serious Sublime Text competitors for a while, but now VS Code has gotten insanely bloated over the years, and also Atom is defunct unfortunately.
I would love to see them build a fully native editor with their decades of knowledge.
They have Fleet which was supposed to be a competitor to VSCode. AFAIK it's written in Kotlin so still JRE (unless they are able to compile it to native?).
