You are kind of looking at it opposite to the imagined purpose I had however. What I was more so imagining was the ability to utilize the support generation of Kiss the way it is, but then for example, be able to turn off support for some text on the surface of the part that is facing the glass. For text like this bridging works great and support is nearly impossible to remove without making it look like junk afterward. However, turning off support is not a possibility because it is needed elsewhere in the model. Adjusting the angle is not an option either because the areas that need the support are horizontal overhangs, but are not bridgeable.
built in Detection of bridging with some threshold would work too I suppose, and might be a lot easier than programming a way for user surface selection of possible support candidates. Either way, I would not see this as a remedy to weak support generation, because Kiss does not have weak support generation, yet this is still a need of some it would seem?
