Request: Dockable notepad

It would be convenient to have a basic, dockable notepad feature in SpeedCrunch, located in the same place one would find the Formula Book, Constants, Functions, etc.

Really, it need not be anything more than a simple textbox, but other possible features of the notepad may include:
- Preservation between sessions
- Creation, alternation between, and deletion of multiple, named notepads
- Some syntax highlighting
- Simple formatting through markup language
