Currently "View File Status" shows only files relative to the directory where it was invoked.
This maybe fine for people coming from other revision control system (like SVN).
A hg user would expect to get a list of all files relative to the repository's root directory, regardless in which sub-directory "View File Status" was invoked.
I suggest an additional checkbox "root" at the bottom of the status window (where the other checkboxes are located) which enables/disables showing files relative to repository root directory.
The standard setting for this checkbox should be configurable in "Setting/Global". Which setting is used as default (i.e. after fresh installation) is ot be discussed. I would prefer to have "root" enabled.
