Vivaldi email users: Do the filters allow you to export or pipe to an external file? As I configure my new working environment, I'm trying to decide between Claws-mail on my Linux laptop, or Vivaldi, and the whole "integrated calendering and an actual business model" thing is endearing.

Just to log it somewhere: Firefox's bullshit has finally gotten to me, and given the raving of Vivaldi users, and their AI comments, I've installed Vivaldi on my usual devices as a replacement.
