Hi, Mark -
I think the documentation change you’re suggestion would be best as a user comment; that feature is fantastic, I hope that you’ll make use of it.
But if you just want entries for the currently logged in user, then CURRENT_USER is a special case scenario, and it is listed here.
Lastly, you don’t need permission to make feature requests, as you know, so go ahead and post it in the appropriate forum. I don’t want to move this thread simply because I’m not entirely clear on how CURRENT_USER fails for you, so the feature request would be good to explain how they differ, to help us understand. =)
