Missing and present medias icons, network, SDCard and more

Description

After some discussions, a possible way to display informations with icons about missing or present medias, from network share SD card, Dropbox service... could be :

A "thumbnail" icon, for all non-internal medias : Network, SD card, Dropbox like services... Currently only network icon exist.
2 universal "emoji" icons for missing and present medias, displayed in the card subtitles. Present icon would appear only for a "group" (group, folder...) with present AND missing medias. Something like X present medias and Y missing medias.

The current situation :
