I was so happy to see multi select layers in the recent 2.99.2 gimp release and was reminded about the old adjustment layers request.
I have faint memories of discussions about this a loong time ago (not pixls.us) and seem to remember that the whole gegl graph thing was supposed to provide an alternative way of achieving the same thing.
I’m not asking for what features are READY NOW but rather about the long term goals. Are there plans for adjustment layers or are there plans for other ways of achieving non destructive editing?
Personally I work around this with copies of layers. When working on A3@300dpi five six copies of 10 layers do have a rather noticeable impact on file size and loading time. But It actually works for me.
