Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
This is particularly nice for VGC as Trick Room is very common and we often want to look at the slowest pokemon in the metagame. This would prevent having to scroll all the way down to the bottom.
This is technically a thing for highest to lowest, but it does feel odd that you can't like, click it again to go to lowest. Most wiki sites have that sort of thing, perhaps it could be implemented the same way? I guess you could just scroll to the bottom after clicking the stat you want though.
