Yes, I alwas look peter's page first)
And I think this script is very useful, becouse if you work on a big models it make life a lot easer, but a lot of people don't know about hiding edges to speed up moi on big models. I think it's one of main approach to work on big projects except Mesh Angle and add detail.. )

And the show edges on selected objects:

script: /* Show edges of selected objects */ var breps = moi.geometryDatabase.getSelectedObjects().getBreps(); for ( var i = 0; i < breps.length; ++i ) breps.item(i).getEdges().setProperty( 'hidden', false ); moi.ui.redrawViewports();
