If you install many softwares you notice that some of them add entries to the Windows Explorer menu. The menu looks crowded after some time and it takes longer to find and click on the entries that you use often.
The software with the rather strange name MMM steps in and lets you rearrange all menu entries. This is done by offering a way to hide entries that you never ever use and a way to add entries that you rarely use to a submenu. My initial right-click menu had ten items listed of which I moved five to the hidden area making it look so much better afterwards.
