Description of Problem:
I'm attempting to export messages from an IMAP server to a mbox file. Once the dialog opens, I select the input and output locations I click "OK."
At this point Claws doesn't indicate that it's doing anything. You can see the progress bar in the bottom right, but it's not immediatley clear that's the progress bar you're looking for.
Having the export dialog display some sort of acknowledgement of input and showing progress would be very beneficial.
