Good app, needs lots of improvements

Updated:
Ive used this app for about a month now but the lack of polish and limited feature set has led me to remove it from my phone. I have since discovered the excellent Zen Timer from Spotlight Six which has met all of my meditation timer needs.

It works fine for my sits but its a ways off to polish. First, it resets my timers when I quit the app. Second, the mindfulness bell doesnt work (even on ios4 multitasking). Welcome improvements would be the ability to change the gong volumes, set # of chimes and the ability to create multi-sit session profiles. That way, one could time for walking meditations and again when the next sit commences. Not completely satisfied but not totally disappointed. I hope development on the app continues.
