There's a thread kicking around here asking for custom profile nodes, but I think it'd be more useful to have custom NODE fields... In other words, the ability to attach custom fields to any node type (forums, pages, profiles, threads, etc) and be able to call them wherever they're needed. An excellent example of this is the CCK module for the Drupal platform. Anybody who's used this knows it's an absolute must have when building any site. This could open the door to everything from video libraries to recipe databases and everything else you might want to build into your community. Please like this post if you want this idea implemented!
