Export Dialog - show calculation time too

[meteorquake]

In the export dialog, as well as the converted file size, it would be good to see the duration it took, as that can be an important element in weighing up what settings to use.

Cheers, David

That’s a great suggestion, David.
Showing the calculation/export time along with file size would really help in comparing different settings efficiently.
