I own a couple JetBrains product for very select things but as much as i enjoy the company i will never use them for my actual code.. because i'm a 20 year addict of Terminal based editors (currently on Helix).
I'd love to see the considerable effort they put towards tooling available to the Terminal oriented audiences. Yea, probably small audience.. but i just often see this stuff and think "What if this was an LSP? I'd purchase it in a heartbeat!"
Especially since multi-LSP editing is apparently viable. Eg Helix supports multiple LSPs for a single context, now. Though i'm not clear on the specifics yet, as i've not tried it yet.
I really want to give them more money. I just don't want to use their UIs for my code.
