Can't cancel out of saving mail as multiple files

[davidbo]

I just selected 600 messages in a mailbox and tried to save them. By mistake I clicked to save them as multiple files. This resulted in me being forced to either click cancel 600 times, enter 600 different filenames or force quit Mulberry...

I picked option 3, for obvious reasons.

I think the right behaviour would be:

1. If I cancel Mulberry should ask if I wants to cancel the whole operation
2. I should have an option to let Mulberry automatically name the files, typically by concatenating the time stamp, sender/receiver and subject
