User-friendly nothing
I made myself a small toolbar that I placed on my Windows desktop. Basically it’s simple form with a textbox and buttons that queries different dictionaries and thesauri - Cambridge, M-W, Reference.com and whatnot. Each time I find some useful online reference, I simply add a new button.
Quite accidentally I came across a nice feature of Reference.com - when it gets an empty query http://dictionary.reference.com/search?q= it returns the definitions of “nothing”. Cool!
