The developer and fixer in tablet form from Tetenal looked pretty cool, and I remember they mentioned something about doing a colour developer that way too, so hopefully the BW set is paving the way, as a colour dev in tablet form would be really useful! I used to use the Tetenal colour dev kits but would stock up at least half a dozen exposed rolls before mixing it, as after a while it'd just drop off regardless of how many rolls I'd developed.
Colour developer in tablet form would make it much easier to use colour film when you don't shoot lots of it!
