Feature request: cut & paste and add new text anywhere

[myneur]

Part of any good writing is editing to rephrase to improve the text.
I don't mean any complex text editor, just a simple cut text, paste it elsewhere, delete or add a new phrase anywhere in the text.

As Blaise Pascal said: "I'm sorry I wrote you such a long letter; I didn't have time to make it shorter".

This app is fun for just playing, but having these function would make it usable for a serious work!
