I often filter my run activities by distance to A) compare performance to past runs of similar distances and B) to find a past run of a given distance. I would filter them by fractional miles. So if I wanted to find past 5K-ish runs I'd sort by the distances 3.0 - 3.2. They have made a change recently to make the sorting only by whole miles. So I would have to filter the distances 3 -4 miles. I have many thousands of runs stored and it makes the filtering almost useless.
I am hoping they change this back.
