Same thing here. I use "Little Secrets" to keep passwords encrypted on my mac. Copy/Paste into a free form card and I'm updated. Except that the file is 7KB long, encrypted, so I have to split it into sublists. Not quite so easy. Quite a pain guessing where the split points belong and naming the sub-files A-G, H-L, etc. The file is just an alphabetized list of sites, each with site name, account name and password.
In fact, the free-form note card is the only kind I use, as I'm quite accustomed to using a text editor to keep lists.
Anyway, unlimited size would be much easier.
Thanks, SW
