I couldnt post the my whole config due to the character limitation.
the Hide Seam function was added before i knew there was a script that could toggle between edge visibility:

script: /*! Show/Hide edges --- H*/ var breps = moi.geometryDatabase.getObjects().getBReps(); var hide = true; for ( var i = 0; i < breps.length; ++i ) { var edges = breps.item(i).getEdges(); if ( i == 0 ) hide = !edges.item(0).hidden; edges.setProperty( 'hidden', hide ); }

I dont use the hide seam function as the script does almost the same.
Think I should throw this one out but it`s hard for me to let things go :))
