I've added a new feature, but I want to wait until I have more suggestions that I want to add before releasing yet another update. I got tired of writing in the notes because it takes so long, so I added the option to enable "note tapping". With this feature on, you can tap in one of the 9 note areas to toggle a note. The note depends on the area you tapped; for instance, if you tap the upper left hand corner, it makes a 1 note. If you tap the middle, it's a 5, and the lower right is a 9. It's disabled by default because it might not be intuitive, but it sure is faster.

By the way, the reason actions take so long is due to Petit Computer's slow drawing and not the number recognition. Each number you write takes about 15 frames to process (1/4 of a second). A whole 12 frames of that is used to draw, while only 3 are used to recognize numbers. This is due to the fact that I have to perform a custom drawing function in order to create a "zoomed in" effect. This is performed by reading each pixel from the area to zoom in on, then redrawing the pixel using a GFILL command to make the pixel appear larger. I've optimized this routine from 17 frames to 12 frames using a whole bunch of gross code, but there's not much more I can do for this. If you have any suggestions for quickly zooming in on a GRP, I'd love to hear them.
