The file permission tab in the file properties dialog could use some love. Attaching a mockup of an improved version with the following changes:

1. Create a section for the user/group/others to make the grouping more obvious.

2. Make labels non-bold, and use left-alignment as per the example in the GNOME HIG. http://library.gnome.org/devel/hig-book/stable/windows-dialog.html.en

3. When a file has no permissions assigned, no longer show "---"; instead show "No permission".

4. Change of wording: "Access files" -> "Read file contents" (as opposed to "List files only").

5. Use the "Apply" icon for the "Apply permissions to enclosed files" button.

6. For the SELinux context, replace "unknown" by "None", and replace the time ("last changed: Unknown") by "Last Changed: Never". This is supposing that SELinux is not supported on the given machine. Of course, one might argue that the context field should be hidden altogether in such a case.
