Actually, there is already a certain type of selection filter in MoI. I hope you have noticed the drill-in mode, jonah.
Quotation: "You can use drill-in selection to select an edge or face of a solid. The first click on a solid will select the solid as a whole object. A second click on it will drill-in to select an edge or face of the solid. Once an initial drill-in selection is made, further clicks or area selects will target the same type of sub-object. For instance, if you drill-in to select an edge you can then do area selections which will only target other edges."
It's strange, but I have got accustomed very quickly that I needn't press the Shift or Ctrl key to adding/removing object from selection.
