Feature: Display subfolders in gallery

[magnushasselquist]

Hi!
Would it be possible to also display any subfolders (as a folder icon) in the gallery. To allow the user to navigate into the subfolder by clicking that folder-icon.

Example:
I create a gallery/folder called "events_2022" and I publish a gallery {gallery}events_2022{/gallery} that will display any images in that folder but also the subfolders "autumn event" and "christmas event". The user should be able to click on the folders and navigate/reload the gallery and display the images from the subfolder. (perhaps with a "back"-button).
