Snippet Creator does just what it's title says. It creates snippets for using while programing with Visual studio or any other development studio that uses .snippet files in xml format. When you are in the middle of programming and come up with a useful snippet you want to save for yourself. Visual Studio doesn't offer an easy way to build the snippet. You have to either open another snippet file and edit that or try to remember all the options available and write one from scratch. Snippet Creator takes the guess work out if the whole process and makes creating a snippet fast and easy.
And if you are new to creating snippets there is plenty of help along to get you through. While not getting in the way of an more advanced user.
