Created attachment 3470 hide gvfs-fuse-daemon mounts xfce4-mount-plugin should hide gvfs-fuse-daemon mounts. The attached patch fixes the issue.
No, it shouldn't hide because some users want to see all mounted filesystems that they would also see with the "mount" command where GVFS is included as well. It _can_ hide if the user wants to hide entries. The user uses the "exclude filesystems" options for that purpose. It works very fine this way.
