I am one of those nagging users. Or rather potential users. I’m a refugee from the crumbling BeyondPod and I can’t find myself in any other podcast players, even after trying about 7 others. I had high hopes from AP because I’ve been a Free Software evangelist and activist for 30 years now, and the closest I could find is Podcust Republic which is not FOSS and not a perfect match either.
1- current state: I haven’t seen anyone try to pick this up.
2- roadmap: nothing other than 197 issues marked “Feature request”. Just the size of that suggests there’s no organized work on the 0project. I see pull requests and commits, but they are building up and not really tackled. Maybe the project is just lacking enough members.
(and sadly no, I am not a developer myself. I do some scripting in devops, but not UI and Android apps.)
