Hallo,
this feels silly, but here's what I'm getting when I save svg's:
I save as regular svg so that (hopefully) the printers who want the vector can print it (usually they complain they need .ai or .eps, bleh).
But Inkscape won't let me close without a prompt to save the file, even though I've already saved it! What makes it happy is also saving an Inkscape version of .svg. To stay safe I'm renaming these since they look the same with the same extension but are differently saved (I put "ink" in the name).

I don't know why Inkscape insists on this. Is it some sort of safety feature? Why do I need both versions of an svg file? Or don't I?

Obviously if I need to go back and tweak an image it's better to tweak the inkscape svg version since as far as I know it stores some more extra information (not sure what, tool settings?), but if it's being created and sent away, never to be touched by me or Inkscape again, can I tell Inkscape "Close without saving"?
