Convert fill layer to paint layer
It would be really helpful to be able to add an image into a fill layer and then convert that into a paint layer.
For cleaning up AO as an example, doing this and then using smudge to neaten up issues would be really nifty.
You can add a “Add Paint” filter to achieve this.
You can do it by setting up a top level paint layer and setting all of its channels to "passthrough" https://docs.substance3d.com/spdoc/smudge-tool-143720512.html

As much as I like Painter for years this is another feature I would call "basic" and "essential". I am currently cleaning up normal maps from an asset bought on TurboSquid. They have very bad seams and with a smudge and paint feature on this imported maps this would be done in a few minutes.
Now my approach is to load them into ZBrush and generate a completely new 3D mesh from it, then clean them up and generate a high poly mesh for Painter and Maya.. not the nicest workaround to get really clean (or better invisible) seams.
smudge tool doesn't smudge filled texture . It smudge only that you paint in "Add paint" itself. We need smudge,blur and clone baked texture to fix baking issues!
+1.. yes please
The smudge tool doesn't work if you do that. Nor does the eraser. We need a real way to convert fill layers to paint layers.
