TPE does it right

Not everyone needs (or realizes s/he needs) TPE. That doesnt stop it from being the most impressive app Ive found since I started with the the first iPhone and first iPad. It is incredibly sophisticated, clever, and thorough, and keeps getting better. The user interface was great when I first encountered it, yet it keeps getting even better.
