Have you ever been in the wardrobe and loved the design of your lion, but wanted to add a new marking? You pick out one that you know will add something great to your male, but at 100% it takes away from the overall design. But what opacity does it look great as? I know that many users such as myself don't want to type in 100 numbers just to find the perfect opacity!

I propose that there be a slider for each marking (defaulting at 100% as per the new update) which will make it easier to see what specific percentage users can set their opacities to.

An example of how this could look is below. The opacity would be shown in a box as it looks current, so members are also able to type in a number to give them a better starting point than 100%.
