I'd love to see ABV on the main list (instead of having to go to that beer's individual page). When I'm scanning through a menu, that's one of the primary things I look at.
Perhaps instead of a straight quantitative ABV, a qualitative indication of whether a beer is unusually weak or strong? Like you, i always look at ABV - mostly because i don't want to get started on some delicious 8% turbo-IPA if it's a thursday lunchtime.
