Unclutters the browser of the elements a user isn't using anyway! Rated 5 out of 5 stars
Great add-on, gets rid of a lot of things even Menu Editor doesn't handle. My only peeve is that it needs a list of all UI elements (accessible through add-ons manager > UI Eraser option button or right/left/middle clicking UI Eraser icon?) because the option hover bar for erasing or putting back an element sometimes closes before one can select an option (I've noticed this especially on the app bar elements).
What would also be great, although perhaps the scope of this extension, would be the option to re-color the backgrounds of the elements one wants to keep visible as well to make certain elements more noticeable or to help group icons who have a similar purpose (i.e., security extension icons, edit icons, etc.).
