here's what I believe canola lacks and what prevents me from using it as a player:

0) preamplifier
the music I have isn't always loud enough to be heard on the radio.
1) WORKING scrollbar (for those of us with 16Gb card with music)
2) dunno if it's here I should ask, but canola should recognize 150 different authors with the same album name as 1 album, not 150 different ones, with one track in each!

10) if possible (if not - forget it) add support for headset buttons (ex: the headset N8*0 was shipped with had 1 button on the mike) - add mapping for that button (eg. next track)

100) if possible (eventually) add a feature to lower the quality of video thus enhancing the performance (something like TCPMP for pocketpc's)

once the first 2-3 demands will be fulfilled, I will switch to canola; not earlier!
