ECEs working fine for me. Tooltips seem to lose ride info text off the bottom (limited to 7 lines maybe?) if the ride name wraps beyond three lines - I've got one where ride name+ECE wraps onto four lines, partly because it was the last ride of the year so the hover box is truncated right. (#3171, 2013 if you want to check.)
Multi year display - perhaps from 20XX to 20YY as an option? Otherwise folk like me who've only been active for a couple of years would get a lot of white at the top ...
