It's kinda annoying to delete .litematica file in explorer every time, when i do 10-20 updates in a row.
Can you add something like messagebox, asking if it's ok to override file and with option "remember answer"?

If i remember correct, you can shift click Save schematic and it would overwrite the previous one.

Yep, it should say Hold shift to overwrite an existing file when your cursor is over the Save Schematic button.

oh i see...
