Appreciate the added perspective, I wasn’t aware. But from my usage of IDEA’s product, I’ve yet to find an extension that makes any major changes to the UI/UX? I see them way more often in the VSCode community. In fact, I find the IDEA plugin system incredibly limited overall. Why do you think that’s the case? Or maybe I’ve been in a bubble and you can point to some interesting ones that I’ve maybe missed?
More than it not being possible, it's not regarded as desirable - IntelliJ users greatly value consistency. The fact that the experience is consistent across different languages is one of the things I like best about IntelliJ. Can you give me an idea of the sort of thing that you'd like to see that you haven't seen?
Here's an example of something I recently added (an inline inspector), that my main competitor (VS Code) said wasn't possible with the VS Code APIs: https://cursive-ide.com/blog/cursive-1.14.0-eap1.html. I have another major feature that I don't have good online doc for, which is also not possible with the VS Code API (parinfer, a Clojure editing mode). This gives you an idea of what it looks like, but this is old and my implementation doesn't work much like this any more: https://shaunlebron.github.io/parinfer.
