Rated 5 out of 5 stars
Five stars for being needed and working fine for the 5 minutes I've tried it.
I noticed that most functions of the tile menu is greyed out when you click on the tab. They work when you click on the contents.
Menu commands greyed out
A command is greyed-out on a menu if it is not currently valid (e.g. trying to 'Untile' a tab which has not been tiled). The tab context menu works slightly differently to the 'Tile' button on the main menu bar and to the tile contents context menu. Right-clicking on a tab chooses that tab to be added above, below, left or right of the currently selected tile. Whereas, for the other menus, the tab to be added must be selected from a list of tabs. In Version 2.0 and later versions, menu commands that are not valid in the current context are hidden (instead of being greyed-out).
