I'll make sure to make it easy for you (or anyone else) to adjust the presets (or add new ones).

I'm going to try for a dialog that has a list of cloth simulations (you pick which ones to apply values to), entry boxes for the numbers, a set of preset buttons, and an apply button.

My biggest gripe about the Cloth Room would be that the parameters don't seem to have (any) units that can be related to the RealWorld, which means that I only have the visual result to go on when trying to simulate a particular type of cloth.
