I would love to have Ironing in Simplify. In Cura it has a time saving algorithm and I'm sure, no need to copypaste code. As a Programmer I see how easy it could be implemented and don't understand why it still does not exist here. When I bought Simplify3D I was sure, a commercial software must be better than freeware. But looking at the results, I'm absolutely unhappy with the surface. When printing emblems, I always have a hole in one of them at same place. Filament-wasting. In Cura with Ironing the results are perfect. It would be so simple ... No lifting, slow low extrusion (I use 5%) with 0.1 or 0.05 (with 0.2mm nozzle) mm distance over any surface that has no printed content in the layer above.
