Better integration with Photolab would be very welcome.
It’s currently very inconvenient to re-export a photo already edited in a Nik plugin; the settings are lost and you have to redo everything.
It would be sufficient to save the settings in the .dop file and, when exporting the photo from Photolab, reapply the changes with the Nik plugins using the parameters saved in the .dop.
When re-editing, start from the parameters saved in the .dop.
