I'm going to post a more detailed usability review when I'm subscribed to the mailing list. For now:
This archive contains four new icons, based on the Tango-style GNOME icon theme, which is licensed under the GPL. They're meant to replace the current fugly toolbar icons. Also, they are 24x24, as mandated by the GNOME HIG and stock icons, not 32x32.
Other changes to the toolbar:
∘ Add separator after "Save Changes"
∘ Add separator before "New PL"
∘ Files -> Add Files
∘ Dirs -> Add Folder
∘ Playlist -> Add Playlist
∘ New PL -> New Playlist
∘ Add Directory -> Add Folder
∘ About -> About gtkpod
∘ Use stock gtk-about for "About"
∘ Use stock gtk-new (instead of gtk-copy) for "Create Playlists"
∘ Use a 16x16 icon for File -> Load iPod(s)
gtkpod-logo.png has been cropped to include just the icon and not the text "gtkpod". It is only used in the about dialog, which is now the GTK stock one - and other GTK/GNOME applications display just the icon.
