I think the list Roach made pretty well sums up what I could reasonably ask for. 

Being able to adjust the Automatic Column Width is probably what I'm most looking folward to, as even on desktop it's kind of a pain to adjust cells so that they show images at max size or dedicate the right amount of space for text. I didn't see that specific feature mentioned in the above list. 

Edit: Specifically for text alignment. I did see the ones for images.
