Dragging a folder from a file manager onto an image could result in a new layer group with any image files as layers
Background This is inspired by the following thread on reddit: https://www.reddit.com/r/GIMP/comments/9gulmk/question_importing_directories_of_images_to_layers/
We have File -> Open as Layers, but this only allow for adding individual image files as layers to an image in GIMP. Trying to add a directory simply opens it in the file chooser.
Dragging and dropping a folder from a file manager to GIMP results in a "Not a regular file" error message.
Idea Dragging a folder onto an image, or selecting on in a file chooser and hitting the open button, could add a new layer group to the image, named like the folder, and filled with any image files contained within the folder.
A dialog could pop up to let the user choose if this should continue recursively, i.e. if folders found within that folder should lead to additional layer groups and be filled with any images they contain, and so on.
