I love Player.fm
They have both an android app with a lot of good features (stream or download, can set how many episodes to download at a time, when to delete old ones, all per podcast and as global defaults, set up your own categories/lists, display order, play order, etc) and an actual web site where you can log in and listen to your stuff as well with synced history, so you can pick up pretty much at the exact spot you paused a podcast on your phone (or vice versa).
KDE for sure. The modern versions look exactly like how I want a desktop environment to look out of the box, and they keep the full range of customizability that a desktop should, IMO, allow it’s users to have. Which is something Windows just kept slowly getting rid of over the years.
I also prefer to have a taskbar that is ever present with a traditional start menu that’s cleanly organized by category rather than the current full screen pop up “activities” search thing gnome does nowadays.
