This is fantastic! Moving around the cursor on my iPhone seems pretty good after the initial learning curve of "dragging moves the cursor from where it currently is, not to where my finger is."
And it's amusing to see all these stacks made by young people - like myself back then! I'll need to dig up my old stacks.

Moving cursor with touch is kind of challenging though.
