Slice View Colorization for 'bad' regions

A nice feature to help identify and avoid print failures could be a specifica color (like red) in the current slice for regions of the 2d slice which are not immediately supported from below by a ‘similarly sized’ region. I have found that what appears well supported in terms of the 3D red shading after putting in manual supports is actually filled with many floating regions that will seemingly fail during printing because their support touch point is slightly off center and does not connect to the ‘bad’ region until a later slice. These red regions would stand out very clearly while scrubbing the vertical slice bar up and down and should be computationally cheap to identify depending on how slices are generated and stored.
