Slider

I'm trying to find the limit for how many fill/strokes you can put on a single object. I thought the slider looked nice.

Quick tip for those diagonal lines on the map:

1) Add a new fill to an object
2) Select 10 lpi 50% (It's in the basic lines pack)
3) Go to Transform -> Pattern only. Rotate 45° and scale to where you like it
4) Lazy diagonal lines!
