I like to write out descriptive parameters in my families. These descriptive parameters can be long. It would be handy if I started typing out the parameter name, and hit "tab", it would complete the rest of the parameter name when I was writing a formula.
Or even if a drop-down box popped up allowing you to select the parameter you started typing.
Just an idea. It could apply to all disciplines of Revit, not just MEP.
