Where is the place for app development related questions?
I am still new to this and slowly getring the MP3 player working. But a discussion with other experienced users could speed this up.
This is a server-forum.
What about apps?
Category #dev sounds about right 
Or if you want it more chatty, visit #nextcloud-dev on Freenode IRC
@John ah, there’s already a dev category. I’d simply use that one, I don’t see a real difference
@BernhardPosselt as with all categories in a forum, it depends on the future amount of Postings there, I guess
Added a sub-category and will move all existing topics over
