Feeds are unweildy for old episodes
When you add a podcast to Funkwhale 0.21.0 via RSS, it creates a channel.
The channel view shows the most recent 10 entries, with a "Show more" button that adds another 10 entries to the list.
Say I've subscribed to a podcast like The Adventure Zone that's about 260 episodes in, and I want to start the podcast from the beginning. To find episode 1, I would have to click on the "Show more" button 26 times, until all the episodes in the feed are displayed on my page, and then play the first one. To come back tomorrow and get the second episode, I have to do the same thing but click on the second-to-last button.
Hitting the play button for the whole feed seems to start from the first episode, which is a workaround, but that's not what I expected since the corresponding list on the page is in the opposite order. Plus then you get the entire feed in your queue, which isn't necessarily what you want, and you have to click to remove all 259 other episodes if there's something else in your queue that you wanted.
You can use search and ask for "Podcast Title Episode XX", but not all feeds will include episode numbers in the titles.
I feel like there needs to be an easy way to find the next unlistened episode in a feed.
