I really like this design, too.
I like how it's compact but still clear. Doesn't take up the whole screen.
Except, it would NEED to show for each torrent:
% Complete, Upload Speed, Download Speed, and Ratio.
Also total megs downloaded and estimated time to complete would be nice.
The status can be shown by the color/icon with hover text for the exact message.
The status bar would need to show total upload/download and probably the last error message recieved from any torrent.
I'd also like the the display in the taskbar to show total upload/download speeds.
One problem with this design is ... where are the upload limits? I guess each torrent can have a right click menu to select and, in Preferences, the Global Limits.
I LOVE how G3 does a lot of things. Take a hard look at it, take out the bloat and clutter, simplify, and there we go. Perfect client.
Things I don't like about G3: No Fast Resume and it preallocates all the space. Some torrents reject it.
