I will be adding lots of user friendly additions to my theme for mobile users next age. I myself updated to an android phone not too long ago so I'll be testing stuff. Some stuff I'm thinking about is bigger fonts and much bigger sized links plus bigger input fields when you're on mobile so it's easier to click and input stuff.
I use mobile a lot for utopia so will make sure its very smooth and easy to navigate off of.
If you have any suggestions lmk tho.
