So that means you don't want the content area to enlarge then?
That makes things a little easier, as we can use the ToggleElementMacro*.
In your PageTemplate, find the following lines:
---------------
<div id='sidebarSearch' macro='search'></div>
<div id='mainMenu' refresh='content' tiddler='MainMenu'></div>
---------------
Swap those (i.e. "mainMenu" above "sidebarSearch").
Then, between "mainMenu" and "sidebarSearch", add the following line:
---------------
<div id='sidebarControls'></div>
---------------
Next, find this line:
---------------
<div id='sidebarTabs' refresh='content' force='true'
tiddler='SideBarTabs'></div>
---------------
Below that, insert this line:
---------------
</div>
---------------
Then you can use the ToggleElementMacro (e.g. in your MainMenu) like so:
<<toggleElement "sidebarControls">>

There is a macro parameter for the startup mode:
<<toggleElement "sidebarControls" "" "" "" "" "hide">>
In order for this to take effect, it needs to be rendered. To make it
render on startup, you could add the macro call to the MainMenu. If you
like, you can hide the resulting button:
---------------
@@visibility:hidden;<<toggleElement "sidebarControls" "" "" "" "" "hide">>@@

On a general note, using TiddlyWiki as a website is a bit of a
contentious issue:

(This page on the community wiki is still incomplete - feel free to

You might also want to look into using PublisherPlugin to have different
modes for authors and visitors.
