Is anyone using custom CSS to make the mobile web experience better?

[mjennings]

I was wondering if anyone has customized their CSS to make the mobile web version of Canvas better. I know I can add a mobile CSS for the app and am already looking at those options to bring the in app experience more in line with what our students see on a desktop. However, the mobile web interface, particularly on phones still leaves a lot to be desired. 

I am pretty comfortable with CSS but wondered if anyone had already plowed this ground and would be willing to share so I did not need to start from scratch.

Thanks in advance & happy Canvasing!
