FYI, this project is listed as "retired." It may no longer function or I may just not be updating it anymore.
Sideshow (previously Sidecar) is a minimalist-yet-oversized jacket for Simplify. Feel free to hack around with it, the source is available on GitHub.
Features
Sideshow calculates screen size to provide a full-height jacket on any display. The width of the player, font sizes, etc. will all adjust to provide a fairly uniform experience across display sizes and types.
It calculates the length of the text for the artist and title displays, adapting the placements to show as much of possible of both.
