Something Jader7777 said in discord sparked this idea, so I’m writing it up here:
What if the Edge tool had a paint bucket/flood fill in the same way that the Fill tool does? One click to paint the perimeter of a single-color region. Perhaps with Shift+single click with Edge selected?
Example:
Open question would be… what should happen in the case that some edges are already filled?
I think I’d maybe expect this:
But this might also be acceptable. Either way though requires some implicit understanding…
Or this case…
This…
Or this?
Or maybe even this…?
I had this idea as well. I was planning on overwriting the color of edges, so you’d get this:
I’m not sure I can think of much in the way of reasons to prefer one way over the other, and my gut currently says this is the way to go 
, so seems fine…
I was also thinking of the case of fully-enclosed “noise” in the shape. So what to do in the situation where you filled the light-grey ground in:
A simple approach might result in:
But I suspect this will never be desired, and you could flood fill the interior objects in most cases if necessary. So I plan to make the result:
I think a Fog of War flood fill will also be good. But I worry about GMs accidently revealing a bunch of stuff accidently 
. Especially shortly after the rollout of the feature.
