It does work Rated 4 out of 5 stars
Note: First time I installed this a while ago, it appeared to do nothing. After installing this you have to do a View, Toolbars, Customize to drag the button(s) to toolbar. Pressing arrow on right of button allows for choosing how often to auto save.This review is for a previous version of the add-on (0.3.2).
