In reply to Andy Ovens - UKC and UKH:
I've found this feature difficult to use as well. It's scrambling that I'm interested in. I think you're right that all the crags in the list contain scrambles when that's what you've searched for. I hadn't realised that before as when you select one of the crags from the list all the different climbing types are displayed and I didn't find it obvious what type each line was.
I've sussed it out now thanks to your post anyway so cheers. It'd definitely be an improvement though if the map would reduce to just show where the scrambles are when that's what you've searched for. Another way could be to still show every crag but change the colour of the ones which have scrambles.
