[Feature request] Ability to set custom icons for folders (and files)

[eauchat]

Linux, Macos and Windows file browsers allow to set a custom icon to a file or a folder. It would be nice if simple file manager allowed to do that.

I don't know if there's a common standard for that, or how android would allow it, but maybe a simple way to achieve it, at least for folders, would be to check if there is a ".icon.png" file in the folder (or maybe ".icon.*", but png is good for transparency).

This way, the user can set a custom icon simply by copying an image to the folder and naming it this way. Or it would even be possible to create an interface to make it by simply selecting a picture in the gallery.
