Feature Request: 'gap tolerance' setting for fill regions using the Inner Boundary Mode

[ArchiRes]

For those times you'd like to use the flood/fill region tool (Inner Boundary Mode within 2D Polygon Tool), I'd love the option to set the tolerance for microscopic gaps between unconnected lines. It's often cumbersome to track down the small gap between two unconnected lines that's causing the filled region to not work. I'd love the ability to set the gap tolerance to something like 1/8" or 1/16". My current method is to select all, Compose into a polyline, and then see which polylines didn't connect.

 

For the short tern, has anyone found a better workaround?
