It would be great if there was an advanced section for parameters, that is collapsed when the build page opens, so that only the basic parameters are visible for the inexperienced users. In my case, I have some parameters that have default values that do not need to be changed unless you know exactly why you'd do that, and people accessing the page get confused about them. Putting them away in an advanced section, so that they are still accessible, but not right at start, would certenly help.
