User inputs for families can quickly get complicated and most families would benefit by having more information about the inputs (parameters). An addition description field would be helpful. Often parameter names are not sufficient to guide user or creator. Complex families would benefit by having a more information for each of the parameters. This field could also be used as "parameter tip" to help guide user with input values.
Example of the type parameters in family editor:
Parameter (name) | Description | Value | Formula | Lock
In addition, a Notes dialog box with a diagram would also benefit the user. Complicated families often require some instruction on how the inputs modify the family. This notes would provide useful information about the family and how it works.
