It's funny because i've updating this mod all day.
I'm doing a total rework of the mod, veeeery nice result, maybe this night is finished.
Thanks for report

Finished, please tell me if you have any problem.

Ok, now I can activate it: it shows popup with a box, and I can activate it (an another popup with configuration at left)
and, if I push "export?" icon (near reset button) - it crashs:
