This question is somewhat related to this other one. However, I am mostly curious what features people would like in a parametric tool. What features of existing tools do people really like; and which aspects of existing tools do you really dislike? What awesome features has no one thought to put into a tool yet? NREL is planning to update the PAT tool in the next year to better align it with the large scale analysis capabilities of the OpenStudio Server. We'd love feedback from users on what the new tool should (or should not) do, what do you think?
