The export commands are great, and work wonderful.
But may i suggest u move the default saving location to a new folder inside documents. Make it a folder u have the game create. Will make it much easier and seem more like an actual feature.
It would also be very helpful if the default name of files was a date + time stamp instead of u having to chose a name.
Keeping the path and name override is nice.
Both changes are really small and takes very little time and effort.
