Just a very simple plugin with a high demand. This plugin works with the essentials API, so basically it's the same /vanish from essentials just with a few more features:
If you go in vanish you get a Compass, Wooden Axe and a book.
The compass and the wooden axe are for WorldEdit.
If you right click someone with the book it opens the players inventory.
Also before you go in vanish mode it saves your inventory, so when you go out of vanish it will load.
/v or /vanish
You MUST have Essentials installed to make this plugin work, it is also recommended to have WorldEdit.
