Visibility handler

As mentioned, just with the addition of the "Enable/Disable in Viewport" button this would be great!

This is so close to being great! The main issue is that this needs to look at the Disable in Viewport setting more than the "Hide in Viewport" as this is a temporary option, but the Disable in Viewport is a keyable option. Would also be great if this plugin copied all the keys from the Viewport Visibility to the Render Visibility, because as it stands, when visibility is animated, this plug-in loses most of it's usefulness.

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
