Google+ Checkvist community posts 2013-2018

I'm a little confused about how best to use the app on iOS devices, specifically iPad. (I have an iPhone as well, but one thing at a time.) I love the way Checkvist works on my laptop, with the keyboard; but how does it work with a touchscreen? The iOS keyboard disappears unless an active data entry area is active - so I can't type enter to add a new item unless I'm already in an item. I saw mention somewhere that iPad users could use the regular web version of the app, and that some enhancements had been added for touchscreens. I'm missing something somewhere.

A CSS question. The first level of topics is in a larger font. I'd like to do something similar for the second level of topics. I've browsed through the CSS but don't see anything specifically for level (though I did find one for "first child". Is there a CSS tag that can be modified for this?
