this has been my main theme for a few weeks now, really liking it. i prefer the clean designs like this!
I'm not sure how hard it would be (or even if it is something you or anyone else would want) but one change that would make it easier to use for me would be:
1. during the searches, when bringing up the alphabet menu, rather than pressing up and down to cycle through letters it feels more natural to press left and right, then press up and down to get in and our of the menu. just a thought.
keep up the good work mate!
