Being able to import stl files this easily to a 3D printer is a big time saving in prototype development. It would be even bigger time saving if the file would be automatically versioned and old version (optionally) deleted.
It wold work like this: In preferences, there are checkboxes "Add version number to exported STL" and "Delete old STL version at export". The first checkbox would cause the exporter gadget stl file to be named "gadget_v52.stl"instead of "gadget.stl". The second would automatically delete older "gadget_v*.stl" files, keeping the printout directory clean.
Please note that "File exists, overwrite?" is not always sufficient. The printout directory might be behind a network (like mine); I don't always notice that the printer driver machine did not yet have the file updated over the cloud. Even mote steps are required to move the file to a memory card, if the card already have the same named file - and sometimes, you do want to print from the card, as computer clitches or even pauses can ruin a long print.
