I can't get the double-tap to work - might try to re-install, but otherwise this app is just what I was looking for!
1) Could an option for Landscape/Portrait for the APPLETT be included? I mostly use the phone single-handed and the avatars and titles are at 90 degrees.
2) Could an option for larger avatars be included? I'd happily accept a 2 x 5 grid per group to enhance ease of use.
