This discussion keeps getting more interesting. I usually agree with Nila on all points, but on this one, I'm 100% behind Doof. The user interface is important. I'd pay money to upgrade (or switch) to software that is easier to use. And the panes work well for me.
I'm also impressed with how open JRiver has been with the development process. Posting conceptual drawings is on another level.
I like the new picture. It's cleaner and looks like it could be easier to use. I'm waiting to see what the Action Window will look like. And I think the dropdown menu might be too difficult to use with more than a couple view schemes.
I took a crack at drawing another way of using tabs. I think it could free up some space.
http://www.samuelkim.com/Public/linked%20data/jriver1.gifThere are four sections:
Player, Tabs, Library, Lower Panel. Each can be hidden or collapsed.
I left blank the audio library section (panes, trees, view scheme groups, etc.), which seems to be the most controversial.
The lower panel is basically Knickelfarz's model, which I thought was excellent. I think it might do the "Action Window" thing quite well.
Playing Now or Playlists can remain on screen with the library which would allow more intuitive list making. You could drag and drop songs into the playlists directly.
Using tabs on top frees up the middle space. With view schemes, playlists., etc. out of the way, you have some more space and flexibility for the audio library. You might fit two or three panes on the left, which allows a longer list of songs on the right.
It also allows separate ui for audio, video, etc.
So the video section won't need the same action window or even the same player.
Being able to hide the player panel also gives you more space.
