Suggestion 1:

Number the files sequentially, in the order in which they appear on the
screen:

Export0001.jpg
Export0002.jpg
Export0003.jpg
...

The number of leading zeroes could be adjusted according to the number
of files that are to be exported, the idea being that the exported files
will appear in a directory listing in the same order, and can be
imported into a presentation manager in this order too.

Suggestion 2:

Number the files as above, but append the original filename:

Export0001-IMAGE006.jpg
Export0002-DSC0999.jpg
Export0003-Jane's Wedding 6.jpg
...

This has the advantage of making it easier to track back to the original
image while keeping the chosen sort order.

Suggestion 3:

As above, but insert the file creation date and time:

Export0001-2004_10_06_12_03-IMAGE006.jpg
Export0002-1966_05_04_16_23-DSC0999.jpg
...

This would mean that a relative to whom I'd sent a selection of
(compressed) images of a family event could ask for a hi-resolution
print of a particular image using an unambiguous filename.

I'd like to be able to override the default filename prefix (e.g.
replace "Export" with "Xmas2007" or "Jim's60th") - indeed the default
filename prefix could be the tag by which the export list has been
selected, if this is the case, although I can see that this might cause
problems if future developments in Shotwell allow selection by some
logical combination of tags!

I'd also like to be able (as indicated in an earlier post) to
drag-and-drop the images into the order in which I want them to be
numbered on export.
