I admire anyone who can write a computer program so well done Kat for having the ability to do something like that, it looks very good, but I won't be requesting the use of it as most of the time I play multiplayer games and am pretty slow anyways, so having to look up things in a virtual notebook might make me even slower.
When you were searching for something before you created your program did you check out Microsofts Onenote? It is a very comprehensive notebook where you can compile copious notes, scribblings, captured images, video recordings, audio recordings, make little sketches, just about anything really. Might be worth a look just out of curiosity.
