I think some of the new logbook features, like being able to filter crags by grade etc, are really good.
However after several weeks, I still can't get on with the way Climbs at the crag appear. I still find the information much less easy to absorb at a glance than it used to be.
The single column works fine on mobile, but on a 16:9 desktop it spreads the information very wide - in particular the star rating is miles away from the name and grade. I find I need to actually look to take it in, whereas when a route simply comes up E1 5b ** or whatever, it's effortless.
I also think that if you're going to have the Rockfax style numerals inside a star symbol instead of the number of actual stars (I'm a fan of the latter, for what it's worth), then they really need to be shaded differently, the way they are in Rockfax guidebooks.
Being able to choose which columns appear is good (I personally don't feel like I need a Type symbol as the grade alone gives that information).
Cheers.
