Here is a bookmarklet for increasing the width of the main LW content region and hiding the sidebar. Create a new bookmark with the link:
javascript:(function(){document.getElementById('sidebar').style.display='none';document.getElementById('content').style.width='99.5%';document.getElementById('wrapper').style.width='100%';document.getElementById('content').style.paddingLeft='0';document.getElementById('main').style.paddingLeft='2px';document.getElementById('main').style.paddingRight='2px';})()
Put the bookmark somewhere accessible, e.g. a toolbar, then click it when you're on a LW page.
You can now zoom in or out as much as you want, and the content will still fill up the entire width of the screen without needing a horizontal scrollbar. This is probably better if you like to have big text or if your screen is narrow. Modify the code if you want a different layout.
How do I put bookmark in a toolbar? I would like to, as I don't use Bookmarks Toolbar.
