Plenty fair enough! I haven’t used Geany in a long time, and never actually ended up trying it as a code editor (rather than just the every once in a while one-off-quick-texr-editor) unfortunately, otherwise I’d have tried to answer your question directly.
I do think that it’s alright to only accept PRs, just so long as it’s made a bit more clear. If I ever ran into a problem with Geany, I’d be completely unable to do anything as I have very little experience with C, let alone GTK and all of the other libraries along with it. I could learn right to effectively flip a few values or even maybe try to correct a basic logic issue - but that’s about it.
That all being said, I hope someone is able to answer your question one way or another! Normally I’d recommend trying to reach out to the project’s chat since they usually have an IRC channel, Matrix channel, or some other place - but in this specific case after seeing the issues you mentioned I’d definitely be hesitant to do that sadly…
