I would like to add another vote for programable names and reverse loop. Something that would be really cool would be a midi clock output from the tempo that you tap on the pedal. Say you want to use the timefactor and modfactor together. Run midi cable between the two pedals or anything else that receives midi sync. Set all of your tempos on one pedal. This would be cool for me so I can sync the lfo on my moog with my delay pedal. You could have it as a patch preference. That way you could not send sync all of the time when you tap tempo your delay. You could even make a preset has no delay and basically just the tap tempo button to slave other devices.
