The bevel modifier is widely used in modelling to chamfer edges and smoothen them out. Bevels are used to correct the shading of mesh, so as to make the edges blunt to give a solid and realistic look as opposed to non beveled objects. However the current modifier does not ensure correct normals and has various listed bugs which slows down artists workflow. Having written my own Weighted Normals modifier in last years Google Summer of Code. I am familiar with the modifier stack and its implementation and can work to provide good quality functionality on the modifier and tool.
