I played a bit with the new features, they look great.
When I tested saving/loading scenarios, it didn't work for me. Using Spanish config (comma as decimal separator) I saves the demo scenario IntroASuW without changing anything.
I see that numbers in scientific notation are saved with comma, but numbers with integer and decimal parts are saved without decimal separators (not comma nor period), giving positions in the hundreds of thousand miles range!!
Fyi, this is the text in saved file:

Anyway, earlier proposed workaround works OK
