Absolutely not functional, stupid to even publish it

The dialog keeps popping up every time, but only on some pages, never showing on others. Every time I make a change in the plugin settings, the pages that it keeps popping up seem to change quite randomly. An absurd behavior!

Also, it won’t let me set anything except 0 or 1 for the background opacity, which is plainly stupid. Of course I want it semi-transparent, why in hell limit the options to only 0 or 1 and nothing in-between??

And to think it used to work properly in the past, it’s like the author is mocking us now. I’m extremely disappointed.
