The calendar widget on Connect forces a pageload of the whole calendar whenever you click on any item in it. Only after bringing you to the "full" calendar page, does a click of the item bring up details about that workout. It would be really, really nice if they just appeared in a popover/tooltip or something without forcing a whole page load.
Off topic, why not open source Connect? I can't imagine the IP of connect itself is particularly valuable (no offense), and features like this would get knocked out in no time by your users, at no expense for you guys besides someone to manage pull requests. Something to think about.
