Add Show/Hide menu option relating to button panel (enhancement request follow on from issue 69)

What steps will reproduce the problem?
1. On some systems, a cleanly installed svnX displays no add
repository/working copy panel in the main windows

2. On a system that does have the panel visible, pressing the "magic" key
combination command-E makes them disappear

3. Present a naive user with the system and ask them to add a repository.

What is the expected output? What do you see instead?
I can't see the panels and I don't know how to make them visible. There is
no clue provided anywhere in the interface. Only by googling the problem do
I find the solution here in issue 69 in the tracker. I would expect a menu
item to be available to show me that toggling the panels is actually
possible. Hell I nearly had to install a different svn client  this
afternoon just because I couldn't find where the button panels had gone!

What version of the product are you using? On what operating system?
1.1 on OSX 10.5.8 and 10.6

Please provide any additional information below.
