When using the browser Create > Join images... option the order in which the selected images will be joined has never seemed very intuitive, and I have often been frustrated when the output is not as expected.
I see now that the 'File list' heading has an inconspicuous small arrow that enables the order of the selected files to be reversed directly, that should be very helpful in the future...
