The quick fur operator now uses the new hair system. It adds a new curves object for every selected mesh, and adds geometry nodes modifiers from the essentials assets that generate curves. A few settings are exposed in the redo panel, including an option for whether to apply the modifier to generate the initial curves so that there is original editable data. The point of the operator is to give people a sense of how to use the node groups and to give a very fast way to build a basic setup for further tweaking. Pull Request #104764
