First I would like to that you for making this tool.
Would it be possible to add some kind of slider control using the current setting as max and the slider control can reduce the effect by as much as 90% of what it currently does now?
Here is a skin I am working on using the GWX Normalizer to generate the Bump Maps.
Currnetly it is a little extreme but kind of matchs the effect of this skin.
G.I.M.P. generated Bump Map + Gaussian Blur(H=0.5, V=0.6).
Even if I edit the Normalized image and add the same Gaussian Blur effect(H=0.5, V=0.6), the GWX barely smooths out at all.
