Hello,this is a very small thing so i think this is the right place to post this. I want to change the SAS Skin scoreboard to have the same symmetrical angle on both sides(before:upper image,after:lower image).Ive looked around and tested some things out,but no luck yet. Can anyone tell me how you would generally do stuff like this(doesnt have to be specific to this skin,more of general help)
