First of all, I LOVE this site. It's nearly perfect, and closer than anything else I've found, for tracking fitness data for a wide range of interests.
But I'd love the following two features (which may already be on your list):
#1. In the "Other" activity type, I'd like to see Distance, Avg Speed, Ascent (I see you've already mentioned that Distance is on the list to be included in Other).
#2. I'd like to have access to more than one "Other" activity type.
I'm mostly a cyclist, and I'd really like to keep separate the time/effort I'm spending on mountain biking vs road biking vs bike commuting on my cruiser. The average speed, total distance, effort, etc is significantly different for the different types of riding. I'm assuming this request isn't common enough to actually create several different cycling activity types, and building up the "other" capabilities would make it easy enough to work around.
Thanks a bunch.
