How about the option to set multiple bools in one node, without needing to make a function or having a long SET chain.
Just Plug in the GET to the node with a checkbox next to it to set it True and False, and add a + button to the bottom of the node to add additional inputs.
why stop at bools – floats and ints would be easy also.
It already exists.
You can save the entire list of variables to be mass-set and a corresponding saved version with all of them in that state to plug it to.
If you are setting large numbers of variables to the same value very often though, it suggests you are going the long way around to handle something for which there are simpler solutions.
Is it not something that can be handled as an array?
