I’ve updated tabs layout algorithms in Tabs Studio to keep the preview tab in the last and right aligned position. For the horizontal tabs layout, the preview tab is now always in the right corner and on the last row with normal tabs, if there is space, or below them:

If you use vertical tabs in Visual Studio 2012, the preview tab is now always at the bottom of normal tabs and to the right:

How do you put the tabs in a vertical list in VS2012? I used that layout in VS2010 thanks to the Productivity Power Tools, but that extension is not available for VS2012.
