Id like to see one improvement on the iPad:
Take use of the whole screen real estate by enabling to continue a long calculation in the next row beneath.
Currently, if youve got a long calculation you write till the screen ends, wait for it to get converted and shrink, and you get like the half screen real estate back to continue. Like this it goes back and forth till the calculation is really really small and takes up more and more space to the right.
All while beneath waits a huge free white space useless due to the lack of rows.
