I remember seeing something in more recent pier's that would/may
this functionality, but I cant remember what it was.
To logout put a link like this in your environment or into any other page:
To browse the contents of the news page add a linke like this:
To add a link to edit the root page (if you have the necessary permissions) use:
*Edit Root Page>/|command=PREditCommand*
I have just found PRCommandWidget (which I wrote, but was hiding in
Pier-Seaside category) I have exported it to pieraddons, and offer it as
a potentially useful addition to Pier-Seaside.
I don't see how this is different to the PRCommandsWidget, except that
it is only able to display a single command?
