Well maybe he is removing your comments because you're being a jerk with your attitude. The extension does what its page says, and it's stupid to be whining about its basic functionality.
I think the add-on has a problem with bg color twitching. I'm not sure if it is supposed to work like this or it's a bug, but in my case it's switching from black background to a white one, and then back to black all over again, which makes it unusable.
