Unfinished sketches (Patreon)

Hey guys, using the patreon app and web page I've come to realise that it gets a liiiiittle tricky to scroll far down to get to some older sketches. 

I'm thinking of coming up with a way to categorize the sketches based on the characters they go with and have links to each of their folders for easy access.

Does anybody know of a service that could help with this?
