An idea for a small but useful Tableau improvement

I have a new idea up on the Tableau Forums, you can check it out and vote it up here http://community.tableausoftware.com/ideas/3447

Here's the idea, its one of those small things that can sometimes drive me a bit nuts.

 - You know how sometimes you are doing something on a Tableau dashboard through server, and either you can't remember what you've been clicking on, or un-clicking your filters would just take too long? Well isn't the 'Revert' button helpful? This little beauty below:

Well I would really love to see this button in Tableau Desktop too, particularly in presentation mode. The reason is that sometimes when I am demoing Tableau I do not have either web access or specifically Tableau Server access, and so I can demo dashboards through presentation mode on desktop. But it can get a bit sticky if you need to start over.

There is a 'Revert to Saved' option but this doesn't always do the trick.
