I highly doubt this is classified a bug at all by Artfunkel, in fact rather a feature. Besides, clicking that folder icon, going to the latest "Recent" folder, and clicking Accept/OK/whatever really shouldn't be that hard to do, and if one would use Blender to do something where it'd be worth it to export it, one would probably do that thing anyway.

Someone who imported a model would be quite surprised if exporting the same model silently overwrote the oliginal file. So I make people choose the output folder manually.
