Considering some of the absurdly short and long runs on this site (Antichamber and Baten Kaitos 100% come to mind here), I was wondering if it would be possible to search runs based on how long the current WR was.

So say I want to see all runs that are under 30 seconds or over 12 hours, I'd be able to filter based on those criteria.

I know nothing about coding so I honestly don't know how feasible this is, but its a feature I would get quite a lot of use out of.

I know this isn't answering your question, but since you raised Baten Kaitos 100% as the absolute longest, I'd like to point your attention to https://www.speedrun.com/wag as the shortest.
