As some of you have pointed out to me Better Google Tasks, the Google Tasks extension that had recently been mentioned by Matt Cutts, is no longer in the Google Play Market.
The short answer as to why: I really don’t know what happened to it on the market.
The longer answer: It is the users that have pointed out its absence. A look through my email and other sources doesn’t reveal any communications about why it was removed.
I do plan on getting it back up at some point but for the moment I have to admit it isn’t high on the priorities list.
