Are you following the development of Export Layers?
https://github.com/kamilburda/gimp-export-layers

I'll just quote what I've been waiting for:
"In-place batch editing of layers is now available.
Procedures can now be applied directly to the layers without exporting them.
This option is available by checking "Batch Editing" under the "Settings" button."

From today version 4.0.1 is available:
https://github.com/kamilburda/gimp-expo ... /tag/4.0.1

Of the numerous novelties, this one is the most important for me - in addition to saving settings, now you can also export and import settings (in two formats: json and pkl).
Due to the ability to freely change the order of their, activation and deactivation procedures and the large preview, BIMP has been left far behind.

Wow! It was already a wonderful plugin, it is even getting even better than wonderful
Thanks a lot Marek for the news

EDIT: I tried it... wow add a filter on all layers and renaming all the layers without exporting, this is a big thing!
