An extra option under the reply category just to say thanks for whatever that nice person who emailed you, just did for you. It would look like this:
Thanks!-- leinypoo13, Dec 28 2009 Typed_20Sarcasm [leinypoo13, Dec 29 2009] I smell a gmail labs application.-- ryokan, Dec 29 2009 Will there be both sincere and ironic options ?-- 8th of 7, Dec 29 2009 ThankS!-- leinypoo13, Dec 29 2009 Gmail Labs: see "canned responses". Not one touch, but close.-- swimswim, Dec 29 2009 [swimswim] excellent, good enough for me.-- leinypoo13, Dec 29 2009 //Will there be both sincere and ironic options ?// And add to that the sarcastic option. e.g. "Thanks for nothing!" when someone does a better job identifying your problem than solving it.-- Jscotty, Dec 29 2009 random, halfbakery
