WT?!

Author asks for payment to use nonexistent documentation at his web site. Promised a year ago (at this writing) to create documentation; only a notice (in a language I don’t know) at author’s web site.

On top of this, button images in the plugin are broken, and the source images I find don’t at all indicate what the buttons are supposed to use.

You’d have to reverse-engineer the code just to figure out how to use this.

A pain to begin with, and ultimately useless (never mind cheap).
