I always find it difficult to remember exactly what I've named my parameters, and it's a P.I.A. to have bring up the parameter windows again.
Also, you don't seem to be able to just leave it up (and it's "Yuuuuuuge"!).
Would be better if when you start typing in a dimension box, F360 tries to guess which parameter you are looking for and give you a scroll list of all those that match. Would also be nice if you could just bring up the whole list from the field where you're trying to enter a parameter.
