The plugin works great for me, and thought I might share this tip.
I was personally using this plugin to look into a slider plugin that was having an error so I needed to disable all plugins except for that one.
The way I did this was to go into wp-content/mu-plugins/ and edit the safe mode loader. I changed the empty array of active plugins to
array('revslider/revslider.php') (since I wanted Revolution Slider to still be active).
This made it so everything was disabled according using Safe Mode except for the one I was inspecting. I'd imagine this could work with multiple plugins by changing the array to include what you want active.
