This small PlugIn will give you the option to remove all comments you put in your templates before the HTML-code gets spit out to the client's browser.

You can activate or deactivate this feature via AdminCP (vBulletin Settings -> General Settings) and even allow usergroups to view those comments anyway (like for Developer, Styler, Admins ect.)

Bugs:
none found yet

Planned feature:
1) remove //-Comments from JavaScript
