I'd like to add tags to exercises and then be able to filter/search for these tags.
Reason: when going on a hike, I'd like to compare with my previous hikes. But to do that I need to find the same route I took before. Right now it's impossible to find the right hike from before if I don't know the exact date I went for that hike. If I can add a tag to the hike (e.g. the name of the mountain or the route name or even the name(s) of other participants) I could easily find those hikes again - assuming that there would be a search function for those tags as well.
Even better would be if fitbit could auto-generate tags from the recorded route and data from maps, but I'd be happy with adding tags manually.
