[TW5] Automatically hide the sidebar when editing?

[LnxGnome]

Hi all,

  Is there a way or setting so that the sidebar will automatically hide itself when I click Edit on an open tiddler?

  I always have preview mode on when I'm editing, and it would make reading/editing a lot easier if the sidebar was not shown.  Unfortunately, having to manually hide and show the sidebar is rather annoying repetative.
