I know that we have the ability to place comments in the blueprints themselves, but for the sake of prototyping or debugging: What about the ability to use the selection box (much like the current comment functionality works now) and comment out the effected blueprint nodes; much like how I can comment out entire sections of code in Java by
/* *code here* */
rather than having to disconnect node links.
This would also open the possibility for having two different sections of blueprint nodes in the same blueprint, and in effect being able to quickly switch between them for debugging or testing.
Call it muting the selected nodes and links for a more accurate term.
