- Bugfix - if no curves are preselected, when selecting the start curve, it does not stay highlighted (flashes too briefly to see).
- Add the possibility to create the tween curves on the current layer. Right now they go to the layer of the first curve picked.
- If the original curves are polylines, an option to simplify output so that the tween curves produced are also polylines. Options “None” and “Sample points” produce degree 1 NURBS curves currently, so those are editable like polylines. However the “Refit” option produces kinked degree 3 curves, if you start editing them, everything goes south…
