I'm using Amarok 2.2.2 using KDE 4.3.90 (KDE 4.4 RC1).
I use Amarok mostly to fetch and listen to podcasts.
* I can't group the podcasts like in Amarok 1. (Create a folder and put similar podcasts in)
* I can't limit the number of episodes to a number larger than 99
* Approximately in the lower half of the playlist or a folder in file view, if you try to select files with SHIFT+Up/Down arrow it only selects two entries. If I continue to the third entry, entry number one is unselected. This problem only affects large playlists/folders.
* In Amarok 1 if you select more than one track in the playlist the total time was displayed in the status bar.
* Pressing Left arrow on a podcast episode (in the podcasts window) should move to the podcast name. Similarly in the music collection. If I show it like Artist -> album -> track, pressing left arrow on a track should move to the album, and pressing left arrow press on an album that isn't expanded should move to the artist.
* Some podcasts like Linux Outlaws (http://linuxoutlaws.com) everytime there's a check for new episodes, Amarok finds a new copy of each episode. I have currently 54 copies of each episode seriously slowing down the program.

Sorry, but if you put so many things in one single report (or forum post), chances are slim that anyone is going to reply...

It's hard to parse all that, and replying requires complicated quoting work.
