I was hoping to redesign my site using the UCSS navigation, but I checked out your demo pages on Android, and while it works okay if I hold the phone sideways, it really doesn't scale well for straight up phones, and it isn't really great sideways.

I was wondering if there is a fix or update coming that will make it more responsive... ?

Hello,

It all depends on the breakpoints and media queries used in your responsive css.
Please check the following responsive demo:

The top navigation is the Universal CSS Navigation Menu. There is absolutely no problem to style its default skins to suit your responsive design.
