Companion program for PlainText app

[Maurice 0]

I'm looking for a companion program for the free PlainText app. This app uses a folder in Dropbox, and makes it easy to edit notes in that folder. It would be nice to have a program on the Mac that uses the same folder and has the same interface, like Noted (http://noted.finotto.org/), but Noted doesn't use Dropbox and hasn't got a global search field. You can ofcourse use programs like TextEdit, but then you have to open and save everytime you switch between notes.

Try notational velocity. I tried it and quite liked it, but I'm an evernote guy myself!
