Ok - so what I was able to do is to make a ctrl+click a sort of "deselection helper" type mode.

Normally when you select curves and edges there is a preference made for targeting unselected curves. This is so that you can do something like click in an area where several edges are radiating out from a central hub and select all the edges by clicking right near the hub point.

In the next beta when you hold down Ctrl this preference will be inverted, and preference will be made to target selected curves (which will deselect when clicked) when there are a bunch of other curves nearby. That should help quite a bit to deselect a curve when you've got a pretty dense area.

This actually helps out the ctrl+drag to copy, since there it will make it easier to drag out a copy of an already selected curve if you click in an area where there are a bunch of curves.


But you can still select things with Ctrl held down if you click on an object that is not nearby anything else - this is to allow for doing a copy by doing Ctrl+Drag on any object including an unselected one.


Then additionally holding down Ctrl prevents doing a drill-in selection so that makes it possible to deselect an already selected brep by doing one Ctrl+click on it.
