The Sansa Clip series players have a unique issue which surfaces in almost all plugins as a result of its display. The screen is essentially just monochrome, except that the top 1/4 of the screen goes through a yellow filter while the lower 3/4 go through a teal filter. There's also about a 2px gap between the sections, and so anything displayed over the gap a) has an ugly black line through it and b) changes colour. Here's a simulator shot of PictureFlow:
(note that the Clip does not display shades as shown here; it flickers to approximate them)
There's already a setting in the UI to enable and disable album title display, but for the Clip it would really look a whole lot better if the album title displayed in the top 16px, with the album art constrained to the bottom 48px, for 64px total (with a theoretical "height" of 66px, meaning the image can sit flush with the top of the "blue" section, the gap provides its own padding). Obviously this might make the reflection look terrible, or even necessitate that it be turned off entirely, but it would still look better than it does now.
