That's pretty cool having the routes labeled like that. Something to think about on our routes.
Lower angle is great especially after working a vert or overhanging route. Or as a good warmup to the same.
For your db the one thing that i find lacking on all sites is a way to make topos easily, or overhead guides, or topos from pictures. Not sure that is something in your wheelhouse or not but it could make your site standout from others.
It's fair to say that nothing I'm doing currently is "in my wheelhouse". All a learning exercise, so I appreciate the suggestion. Adding some functionality so someone can create a topo from a picture is definitely sometime I want to include.
