In reply to steveb2006:
This is a tricky one, as some people would expect it to persist, and some not. It should be possible to add it as a saved state (like the ordering of the table already does), but it would have to be handled sensibly. Ie how long would it persist for, should any filters also persist for other crags?
I’ll add it to the list to investigate, and it may end up being a user option to enable persistence.
For now, is recommend using tabs. Either hold control (cmd on Mac) while you click on a climb link, or right click “open in new tab” instead. This will keep your crag tab open and filtered while your browse the climbs in other tabs.
