Hi Micha, what I intend to do is to start the meshing automatically like it currently does, but allow you to edit parameters while the meshing is happening, and if you make any changes the current meshing will be canceled and a recalculation started.

I have infrastructure in place to handle this automatically for regular commands, stuff like Fillets, etc - that's why there is generally no need in MoI for a "preview" type button. Any parameter changes within a command get applied automatically.

Mesh creation is different enough from a regular command that I need to do some extra work to make it function in the same way. I didn't have time to do that for v1 but I should be able to handle it for v2.
