It would be nice to be able to paste plain text into notes, history, or schedules. Right now if I paste information from a website or email it is more often than not in a completely different font and size. I have to manually change it back to the default for the note, which can get annoying, so that way our notes database doesn't start looking utterly randomized.
Being able to paste in plain text rather then rich text would be very nice. That or just be able to turn off rich text on a per note/schedule basis.
