There has been a submitted Idea for this before, but it has been archived.
I'm using several parameters for a design and I want some major parameters at the top of my list. It would be great if we can manually change the order of our parameters instead of a default by order of creation. Also, being able to change the units after a parameter is created would be helpful, I forgot to set a parameter to DEG and had to recreate it because I couldn't re-select the units.
