I would like to see a spreadsheet display option in the Family Types dialog box. Variables down the left side (rows), types across the top (columns). Many mechanical equipment catalogs and shop drawings are organized this way, and it would facilitate editing the variables. Creating a new variable (parameter) should be as easy as typing the name in the first column of an empty row. Creating a new type should be as easy as entering the new type name in the first row of an empty column.
