I've been using Garmin Connect for almost 3 years. I would like to be able to see graphs of activities (and weight) beyond one year. Would also be nice to overlay graphs for comparison.
Yes, under the garmin classic the weight shows for "all days" but under garmin modern it only shows the last 12 months - pretty useless for data tracking! Also, the colour scheme for weight (faint yellow) is near impossible to read on a monitor. I often think that modern view is not much of an improvement from the classic view.
