I have had some people request separate categories for US and JP. I've demonstrated that filtering on Regions would do that, but have been told that's not "good enough". I bet that if I could give them a "one click URL" that pre-filters to a US/JP only board, that would be "good enough".

Has this feature been considered in the past? Does it sound feasible?

They are adding URL parameters with the new leaderboard rework for all of the variables and filters

Awesome. Is there a thread or a post about the rework? Would love to see what other things are being made, or if there's an ETA.

The URL parameters is leaked info😅 @Meta has said this in the supporter forums [quote=Meta]In the last couple weeks, we have reflected on about two years worth of feedback surrounding the current Speedrun.com leaderboard experience and sent out a survey created by our UX Designer (big thank you to those who filled that out!) and we are now full steam ahead on the leaderboard rework! For those of you who have taken part in our UX interviews, thank you so much once again! They were a massive help.[/quote]
