Fill Jagged Border Edges

Hello IStonia.
First of all, I'm already considering selling my Silo license, because your baby is sooo bloody better than Nevercenter's. Thank you for this, and keep up the good work, you code wizard!!!
Anyway, I'd like to report a minor bug I've encountered.
The Fill Jagged Border Edges command will produce orphaned vertices when user presses Undo key to undo the fill operation.
And by the way, is it possible to enhance the functionality of this tool? It's description says it maintains the curvature of the mesh, but I found it does it only roughly. Take a basic cylinder for example. Delete some faces from it. The tool will recreate them, but their curvature is far from being perfect and the original shape of the cylinder.

Thanks!

I tested this, it does it here as well. Can't attest as to the quality of the tool as I've only used it a few times. Should integrate it into my workflow more, it seems nice.

edit: added it to my edge bridge streamline tool, makes sense there.

The bug is fixed. But I couldn't think of any better way to control the shape.

I believe the F2 addon in Blender might have some examples of how to predict the curvature. I don't believe Blender plugins support encryption/obfuscation, so if you're interested you could take a look at the code?

Thank you IStonia. Much appreciated.
