Interesting mention of Sidekick Plus, there was a complete SDK for it which I don't think ever got released anywhere (I had a copy as I was working for Borland at the time). It allowed multiple documents to be open at the same time.
It allowed to copy text from screen and paste into its editor, had a modem terminal app, contact app and a calculator. It was a joy to use!
