We did have ideas of using the seamless background tuning (well, it tunes/retunes very fast) that is usually used for RDS updates to build a "map" of the entire FM range in the background (listening to FM, or listening to MP3s) - ie, you'd be able to get a screen-wide signal strength map, with 88 on one side and 108 on the other... could display this when doing the manual tuning.

I suspect it's just wish-list at the moment, though...
