I have been using Revit for almost a decade and I have to say one of the most obvious things that could be a real time-saver would be 2 options in the materials dialog for cut patterns. 1 for a horizontal or "plan" cut and one for a vertical or "section" cut. Obviously detail components will always be needed for detailing, but wouldn't it be awesome if the fill patterns on the section cuts actually represented the materials for things like brick or block. Even if it wasn't a pattern but a way to associate specific detail components with that particular material.
This can already be done in regular families, as well as some system families floors and roofs with deck profiles. From a programming standpoint Im sure it would be difficult but I'm sure it could be done.
