Free is a very good price. I would like to use Pastor, but the lack of password obsuring (which I guess others have complained against) makes me wary. If I have the app open and someone walks up behind me, they could see all the information in that entry.
You could use an "unbullet" command and timer, where the command would unbullet the password, then it would re-bullet the password after a set amount of time, say 15 seconds.
Alternatively, I'd like to see the Entry tab content in a drawer, thus obscuring all the information until I want to see it.

Just a few thoughts.
