Every program these days seem to put an extra item or 2 in your context-menu. It is all under the guise of being helpful, but often it is to get the Company name (or product name) in the menu. They see it as a place to advertise. And of course it is difficult or impossible to remove these items in an easy way.
The context-menu quickly becomes a mess!
Most of these functions you never use. Some you use sometimes. And some you use all the time. Mmm lets you get rid of the items you never use. Lets you move those items you rarely use out on a submenu. Keeping only the functions you often use in a tidy and small base menu.
