</label> <label>This effect joins the Bezier curves with straight line segments.
If the end nodes are close enough, they are merged into a single one.
With the optimized option selected, the new curve starts from the top
most curve from the selection. The curves are then joined based on the
distance of their closest end point to the previous curve.
Additionally it allows to create different tabs / dimples for lasercutting.
This extension is originally based on 'Join Paths Optimized' by Shriinivas.</label>
