I have implemented a rich text console , using the IConsole interface.

Still has bugs, but helps noobs like me in locating methods in a module by simulating intellisense.

Also has support for up & down arrow keys to scroll through history & the default copy paste of Rich Text box.

If you like to play with it you can download it from here.
