- (2012-03-24) Scott Kingery: This is pretty nice. Does what it says, collapses the top of GMail and moves everything up. If there was a way for it to expand into the newly created free space at the bottom of the screen it would be really useful.
- (2012-03-23) Todd King: Just installed but so far so good. Any chance for a GCal version?
- (2012-01-17) Yes! It does what it says it will do... gives you more room. More room is good!
