Only issue for me is that even in 1/2 speed its moving to fast for my eyes to focus on the numbers. So what I need is to have the lines separated like musical notation so that I can look down and read ahead and see the next line coming, without the numbers moving, so my eyes can focus.
Pretty much everyone that reads music/tabs reads ahead of where they are actually playing its probably something you do subconsciously without realizing it but being unable to do so makes reading tabs much harder.
Other then that this is really really cool!
