(The following is with 1password for iPad.)
I have login notes with long notes entries. In one case, I have a note that is 92 lines long, but only the first 90 lines are displayed (consisting of around 1980 characters). In another case, the notes field is 202 lines long, but only the first 99 lines are displayed (consisting of around 1264 characters). To see all of the lines, I have to edit the note (and then, I get a teeny tiny 6-line window in which to view these long notes).
