Hi,

A modifier to override snap could be a useful productivity feature.
For example pressing "Alt" or "Ctrl" while clicking could temporally turn of snapping.

In the same train, a way to "isolate" a snapping mode in the object snap flyout would be handy.
This could permit to select tangent mode, for instance, without unclicking all of the others one by one.

Recklicking with the modifier could also revert to previous settings.

Regards,

Marc
