To add scrolling to the pop up category menu you can also add this to your changes. This works for if you have a ton of categories, like I do.

To the bottom of mobile_categories.tpl add a new class to the ul, I added "mobile-menu-d" as my new class.

    <ul class="mobile-menu-d">
      {$smarty.capture.menu}
    </ul>

Then in altskin.css add the following under "@media screen and (max-width933px)" somewhere around line #3230 of altskin.css.

.mobile-menu-d{
	max-height: 400px;
	overflow-y: scroll;
	overflow-x: hidden;
	
}

The height is editable to taste, I found 400px to be a decent height on my phone but it may change later. It works with touch scrolling on iPhone and Android for what I can tell, but I have not tested it on a huge range of devices.
