Besides, on Linux at least, the path shown when clicking the 3 dots, which remembers the last export location, is not the default path if you just click Export. It gives you the impression that the default path is the last one, whereas in fact, it is Home.
So you just export a bunch of pictures then realise they are all in Home, not in the last location although it’s what is shown when you click the 3 dots.
Showing the output file directory would reveal this bug, so it should probably be fixed at the same time.
