Love the next context menu feature. Always hated the fact that nearly every app would add a menu item to the context menu. Only suggestion I have is try to retrieve the caption of the menu item and display it as a column. This would help people figure out exactly what they can disable and enable.
i.e. TortoiseSVN has 3 menu items, "SVN Checkout...", "SVN Repo-browser" and "TortoiseSVN" I would have to play around with the disable and enable to disable the exact one I wanted to.
Anyway would be a nice addition. Thanks for this great new feature.
