While Pandora has an option to sort stations by most played and most recently played, this doesn't help me find my go-to stations easily. This got particularly difficult to manage ever since the Alexa integration automatically creates a new station every time I want to listen to a particular artist or song.
I would like to be able to mark my stations as "Mine" - i.e. my favorite stations - and be able to sort or view these under the stations browser. Least recently used doesn't work: The auto-created stations clutter the view at the top. Most played doesn't work: New stations are at the bottom of the list. Renaming them with my name on the front of the station doesn't work: Pandora stations can't be renamed and the station search doesn't do a good job of pulling those anyway.
It's a pretty big implementation problem for me - the solution has been "browser bookmarks" to my stations, which is hard cheese.
