I just installed 1.4 on my fully unlocked HTC7 Mozart. The app crashed the first time I tried to sort by size, but works fine now.
Feature Suggestion: Allow us to export a list of installed apps to skydrive/dropbox/box.net/minus.com/or other cloud storages.
Phone: Nokia Lumia 920, retired my HTC 7 Mozart
Tablet: Acer Iconia W510 (Windows 8) - finally got rid of the horrible Samsung Galaxy Tab (P7510)
