Hi Andres,

Thanks for your feedback. Showing everything in scope that matches or
can match the type of a hole is certainly something I am interested
in, but I'm afraid it's out of the scope of this project. I think
finding the types of the holes is a good first step that should make
this feature easier to implement later.

Best regards,
Thijs Alkemade
