Great plugin.
I'd like normal, stack, and active guides to accept arrays as you've done with backgrounds. Then you could do something like:
"guides.stack.color.dark": [
"rgba(252, 30, 112, .30)",
"rgba(166, 226, 46, .30)",
"rgba(96, 211, 232, .30)",
"rgba(253, 151, 31, .30)"
],
"guides.active.color.dark": [
"rgba(252, 30, 112, .90)",
"rgba(166, 226, 46, .90)",
"rgba(96, 211, 232, .90)",
"rgba(253, 151, 31, .90)"
],
...for an effect like:
