Allow thumbnailing photos from mobile devices using the MTP protocol (don't consider it as a remote GVFS protocol)
If you connect an Android (or LineageOS) phone to a computer running GNOME, you can easily grab the photos from its file storage in MTP mode. Nautilus handles that fine, allowing to mount the device and access paths such as
mtp://%5Busb%3thedevicename%5D/Internal%20shared%20storage/DCIM/Camera/
The problem, however, is that they are unmanageable from a user perspective because you don't have thumbnails showing up for the photos. So you end up with this:
Since the phones typically show only the thumbnails and not the filenames, and here I have only filenames, it makes it nearly impossible to "manage" a photo library by batch-moving a portion of my photos to my computer while leaving the others on the phone, because I can't differentiate them without opening each photo individually.
Could we please have Nautilus consider that MTP:// is a local protocol instead of a remote one, and thumbnail the files as appropriate?
