I totally agree. Either that, or add more stuff into the Articles section. But I suppose that it will be easier to find if it's on the forums.
And for the "keyboard tabs" part, Guitar Pro actually has that kind of feature. Atleast it allows people who can't read sheets to learn some songs
But, if you can't read sheets, I think it's better to try and learn that, instead of cheating and take shortcuts to learn new songs, eventually you will need to be able to read sheets anyways.
I've cheated quite a lot on that part, I've learned almost all my songs through Guitar Pro, which I kind of regret now, since I have a homework over the summer to learn a song (that I've never heard) only by reading the sheets. And as you can guess, I'm struggeling a bit with it :P.
Aaaanyways, feels like I'm getting a bit off-topic... I'm totally on your side on this suggestion
