Other editors aside from VSCode will be supported right after the basic features have been implemented.

Not really a priority ATM but I just want to check it out how it goes in the latest update. So far it is now working with the warning message appearing:

Good news. Need a bigger compatibility with the IDE, not just notepads.

June 2022 update: still the same lol we'll just need to wait for Jetbrain Fleet then

Intellij has had a plugin for a little while now, and JetBrain announced they are adding LSP support to Intellij in the next release.
