For grammar junkies like me ( seeing/hearing a grammatical error has the same effect as the sound of fingernails on a chalkboard.), this is the ultimate Godsend. I sincerely can't say enough thanks. This snappy app also removes my ego-centered issue/phobia of accidentally sending out my writings with grammar sewage within because I somehow missed one (or more - eegads!). This is a sanity saving tool I want on my browser forever and a day. Outstanding job, dev!
