Good to see a release of Plexamp for Linux. Just a couple of observations:
Gapless playback! - (For all that is holy please sort this for android / other apps so I can play music properly when not on desktop computer).
Looks really nice
Integrates into Gnome 3 for notifications lovely but...
Because it installs as an .appimage it doesn't integrate into the rest of the desktop environment correctly (Gnome 3 on Fedora 27) - Eg there is no right click menu to get to any of the settings in the menu bar / system tray - Therefore I cannot change size, change source or check for updates etc. Default layout a little too small. (I wonder if I could change it in settings file but that's a bit of a bodge). I would like to see what other size layouts are like to use!
Recently played and recently added do not change - I think this is my setup. I have three music libraries added - Music, Audiobooks and Podcasts. It seems to only show info from Audiobooks, being the first library. (Off the point but also build in proper support for Podcasts / Audiobooks into Plex)!
The above also affects Library Radio and Time Travel Radio - Will only pick up from the Audiobooks one and not the others.
