Easier erase function in drawing mode on mobile devices/tablets
I was using the Khan Academy app on my tablet last night, but when I used the drawing function to work out my calculations, I found that the erase tool only has a fine point on it. This made erasing errors, or freeing up space to expand calculations quite tedious. It would be nice to have a click and drag function to select large areas to erase. I also noticed that there is no drawing function at all on the iPhone app. A drawing function would be useful for when people want to use the app but don’t have immediate access to pen and paper. Thanks :)
