For easy reference, here are my wishes and bug reports regarding now playing tab, some of which I already posted on the v3 GUI discussion thread.
Artist Picture/Album Color Mix/Large Album view- Font setting for lyrics & artist bio should be consistent both for left and right main panel (main panel on Large Album view)
- Make sidebar player element available (know it's planned)- Support row span setting and split value setting for track info panel just like those of track info element.
- Support display of web content via web links like v2.5 when web browser plugin is enabled
TM view- When you're on a TM view, right sidebar shows its header bar only (http://i.imgur.com/qDaCGtE.png)Album Color Mix view- In my opinion this view would work best as a background for something else. Consider providing a set of options on what to draw over that background: artist picture, album cover, visualizer.
