Visibility handler

After enabling the plugin, I don't know where to look for the plugin interface, and trying to click on hide doesn't synchronize the hide rendering, and the plugin use leaves me confused

Hi! I think that in order for this add-on to be truly amazing, the matching of viewport and render visibility settings shouldn't be an operator inside the View menu of the 3D view (which btw is not documented in the add-on info, I had to search for it, and it's also a bit of a counterintuitive location), but should be an AUTOMATIC setting of the add-on preference, so that when I enable the add-on, the visibility settings match automatically, anytime. If the objective of this was to eliminate the hassle of remembering to turn on/off the visibility for rendering or vice-versa, this simply substitutes it with the hassle of remembering everytime to go in a menu and run the operator. Good idea for a long-standing issue, not really great implementation in my opinion.
