Hello 🙂

For five years now I’ve been using a plugin that displays thumbnails of my own programs in IntelliJ Idea. The current version works with OPENRNDR, a Kotlin based creative coding framework. It helps me visually find my programs, as each Idea project may have up to 100 or 200 sketches.

I think it wouldn’t be hard to make it compatible with Processing and other frameworks that run in Jetbrains IDEs. Currently there’s some code that tries to identify which Kotlin files are actually runnable programs (and not just classes or helpers). For Processing it should also find Java files. There’s also a list of keywords to ignore in the integrated “search engine” (words that appear in every program, which would be a useless search). Those keywords should be made to match frequent Processing instructions.

You can see how it looks like here:

Is anyone working with Idea + Processing who could benefit from making this plugin Processing-compatible?
