Not working at all. Very long manual probably outdated.

After you instal it (right click the add button, save to file, then instal from file) and click on options, there is a message that it's mostly non functional and asks you to complete a survey about what features you want etc as they're considering whether to update or discontinue it.
I suggested they put that in the addon download page!

Theres only 2 buttons: background colour and text colour I didn't try them.

Does not work and cannot resize fonts as admitted by authors.

Doesn't work, should be removed.
Is obviously no longer being developed further.
Latest comments on their website are from 2014.

Doesn't work. Waste of time
