Link to external page of episode in channel
What is the problem you are facing?
I listen to a lot of Podcasts via their RSS-feeds in funkwhale. Since the description gets cut off at (I think) 5000 characters, with a lot of those I can't read the whole show notes from funkwhale. Also sometimes I like to open the page of the podcast-episode directly to save it.
Thus, it would be nice to have a link to the original episode page somewhere in the UI. IIRC (though I'm unsure since it's been a longer time since I've used a podcatcher) this Link usually gets provided somewhere, so it would probably be a matter of parsing this Link and displaying it somewhere (maybe similarly to the "Mirrored from" in the Channel-Overview.
What are the possible drawbacks or issues with the requested changes?
I don't know about the specific implementation, but since episodes in channels are basically just tracks, this might be a change in the model of tracks which only gets used in an absolute edge-case. Also it might split up the implementation of the frontend for tracks.
If this is complicated to implement, it could be a good idea to just put the link in the beginning of the Description field. Thus it would be present in the track and the only necessary implementation-effort would be to add the link to the description while parsing the RSS-feed.
