+ path with clickable components
+ human readable size, mode, ...
+ mime icon with integrated thumbnail creation
- link widget uses now vfs-mime for it's icons
- thumbnail creation is now switched on with size 32px by default, it can
be switched of by the admin or user, in doing so explicitly
- mime-icons are moved from filemanager to etemplate, as not everyone
installs filemanager
- filemanager has now 3 display modi:
+ Current directory (with subdirs always on top)
+ Subdirs sorted in
+ Files from subdirs (shows recursive all files and you
can click on the path components thanks to new vfs widget)
