I would love it if Revit added a feature where you could layout a block of text and right click insert a link to a specific view and it is coded to update if that view number and/or sheet changes. For instance on an RCP plan I have an outline of the roof hatch/shaft and would like to put a text note that says "SEE DETAIL # ON SHEET XYZ" similar to how word has the ability to do a table of contents and if you move sections or chapters around the table of contents can auto update. Also not to unsimilar to a detail callout when a referenced view is used.
