I read the following dev email Removing 'Backgrounds and Emblems' and when i read this part:
Note that this does not completely remove the ability for extensions (e.g. Dropbox) to add emblems programmatically by using the libnautilus-extension library, just the user-added emblems from the properties dialog/emblems sidebar.
There is ability to bring emblems programmatically. So, How can i use
libnautilus-extension library to add some emblems like Dropbox does? Or is there any tweak tool for this?
