I cannot open doors or access chests/furnaces/dispensers while vanished. Is this intentional? If so, please add an option to disable it.

Just realized, I can't modify the world at all while vanished. There are no errors in console, and I have op and the * permission node. Once again, don't know if it's intentional or not, but please allow an option to disable it if it is.

You gave yourself all permissions, which means you specifically enabled everything. Please read the permissions documentation before asking for support. http://dev.bukkit.org/server-mods/vanish/pages/permissions/

Ah, sorry. Last time I used this plugin was before this new feature was added.
