I would love the ability to select multiple curves or line segments to use for one Wirecut. The wirecut is in itself a very powerful tool.
This could be selecting three closed curves, in the same plane, and cut into a solid in one go.
This could also be to select linesegments that are connected but not merged into one curve. This would enable to try a few shapes fairly quickly without having to do join - explode every time. This should also work for grouped lines that are not “joined”.
