First of all: this plugin is great!
even tho there are some things i dont enjoy that much, like artifacts when using time machine / time machine 2, basically a weird sounding low-mid range (doesnt happen with the mono stuff but if you have a stereo kick..yea) and that, depending on the kick sample, some kicks sound shorter when pitched higher, which doesnt really happen with the mono algorhythm.
also it would be cool if you had 3 zones, one for the really short attack of the kick, one for the punch and one for the tail, so that you can pitch the punch & the tail independently from each other. Also a loop-function would be really cool to loop a certain part of the kick after a certain point.
Thats about everything that came to my mind so far, anyway, like i said: great plugin and im sure it will get even better!
