When I go to override class parameters in a host group some of my parameter names are over 18 characters long and I am unable to determine which parameter I need to change. The max width of the parameter name seems to be 18 characters which should be increased to 30 or more. I think the new Use puppet default feature took away a lot of the space.

Additionally there should be a tool tip that shows the entire name if the field needs to be truncated.

I might recommend that you make the override parameter list a table and allow the user to resize the column width as needed.
