Feature to switch the current bt4 profile by typing something like '/bt -profile MyPVPProfile' would ease the use of bartender a lot if it comes to macros. For example: I'm respeccing at the moment with a simple click on a macro button. and that changes the spec, the equip, the stance and the profile of my bar addon (which i'm using since one week exactly because it has got the slash command feature).

You can actually do this, even though most people are unaware of this.

Type "/bt profiles" for a complete list of the options.
