The organization of the parameter list is locked in to the order i which parameters were created. Better, this list should conform to the standards implemented for spreadsheet-type lists in virtually every place one encounters them - the standard is that these lists are sortable on any column by simply clicking the header for that column. Repeated clicks cause the list to toggle between ascending between descending order.
As it is now, if one has a sizable list, finding the parameter of interest is a very tie consuming effort. At the very least, the list should default to standard collating sequence based on parameter name.
Another thing which you might consider is to allow importing/exporting a parameter list from/to an Excel spreadsheet.
Such improvements would save designers massive amounts of time.
