thanks for getting back to me. i haven't started using command line yet, but one of these days...
1. an easy printout or export/import function for backup in another place would seem necessary for me to commit to a password utility. otherwise all the work of inputting my passwords might be in vain.
2. i guess i would be able to test diablo backup by un - and then reinstalling trustme, so if that would be useful please let me know.
3. after installing trustme and abiword a few weeks ago, i had a new weird battery issue, which hasn't reocurred since i uninstalled trustme, but that isn't much evidence for anything. are you using it on a tablet yourself?
