Yeah, I appreciate the UI elements. Tragically, they just kind of make you feel more stupid when you do eventually make the mistake. Most UI elements like that eventually succumb to "change blindness". Your brain just stops noticing the elements on screen that are always there. I think any attempt to make them more attention grabbing would risk them becoming annoyingly distracting.
Obviously, "pay attention and don't make the mistake in the first place" is the best advice, but prevention is never 100. It's an issue I've seen people have on all the major skin editors. If I have to use the copy button and make custom brushes for each face, then stamp them back on the correct way, it becomes easier to fire up GIMP and and do it that way.
Skin Editor Reverse Skin option
So call me stupid, but I have on several occasions gotten well into a skin before realizing that I've made it backwards (face on the back of the head, etc...). I know I'm not the only one who's made this mistake. If it's at all possible, it would be great if there were a button in the skin editor that simply flipped the skin around the right way.
Flipping them around by hand in an art program takes me forever.
Thanks for the great site and all the hard work you do. Love ya!
