It was not great when I tried it a few years ago. It seemed very low-effort, basically a glorified web app shortcut. The only feature I liked over my go-to podcast app (PocketCasts) was that it worked much better with the Google home speakers. Then I heard YouTube music was rolling out podcasts and I knew it was only a matter of time until they killed it.
Good choice with Mint, I think its the best distro for people transitioning from Windows.
