On a desktop, the logical path for podcasts would be ~/Podcasts/Kasts, or customisable to be re-routed to a specific folder, like ~/Audio/Podcasts.
Overall, however, given the ease with which a podcast player can play the files and simply patch into the computer with bluetooth - I see no real problem either way.
It does look confusing as a new Android user that it’s not trivial to simply browse the files… but it’s really very rare that I did this (last time was when I decided to download and export a complete set - then I just went to desktop anyway).
Overall an excellent application, kudos to you
