Feature Request - Screen-Filling/Text Formatting

[AayamSharma]

Hi, there is a lot of unused space right and left when using the ipad on horizontal mode, is there a way where this could be changed to fill everything? Maybe there is an easy fix?(crossing fingers that this is just a pre-set width adjustment issue, that can be easily altered)

Secondly, is it possible to get the text size alteration buttons to work? the text feels kind of small right now, makes it a little uncomfortable to use.
