Allow us to set PrimaryPart Line Thickness to 0

The smallest you can set it to is 0.001 or else you’ll get the “Input value must be less than 0.05” error. I take it that’s your out-of-bounds error but you didn’t imagine anyone would set it to 0. Line Thickness should be able to be set to 0 in order to turn it off.

I like how they added a line thickness setting. Maybe a Line Transparency setting?

Would be awesome to see similar settings for selectionboxes (those huge blue lines in your image)
