Thanks, I'm wondering if there are more tutorials about writing plugins. There are a few shortcuts that do not exist and I'd love to implement with a plugin.
In 2014, I have written a just for fun plugin in about 2 hours (check out my write-up [1]). I've followed the "How to make an IntelliJ IDEA plugin in less than 30 minutes" [2] guide back then. Unfortunately, this guide seems to be outdated, but now there's an official guide [3].
