Pretty niche feature, but it'd be cool if there was a way to adjust the order of the results on the search results page.
For example, I was looking for a recent FA of Dan Varian's here https://www.ukclimbing.com/logbook/search/?query=fa(varian) but it's quite a long list so it was hard to track down. If there was an option for ordering the results then it would have made it faster.
In my case ordering by FA date would have been useful, but I guess you'd want the option for ordering on different fields: grade, crag (alphabetical), route (alphabetical) etc.
