I wrote an extension to bring lists out of hiding. Haven't done anything for the new mobile web app yet, waiting to see if they'll make an appearance officially soon.
Unfortunately, I don't think Twitter gives lists enough attention because it's an underused feature, but at the same time, if lists are unusable.. of course no one is going to use them.
Nice, I remember seeing this on ProductHunt. I'm working on electoralhq.com which provides Twitter Lists search and management tools. Shifting into building scoutzen.com now though in order to be more independent of Twitter Lists since they get such little attention from Twitter.
