The only reason I recommended LP in this thread is because it supports up to 3 docks that you can swipe between them. And because the OP is interested in space-saving ideas, each icon on any of the 3 docks can serve 2 purposes: a single tap action and a swipe-up action. For example, I have my GTasks icon on the dock, 1 tap launches GTasks, swiping the same icon launches Calendar; for the Gmail icon, swiping it launches the compose window. Of course all these actions are completely customizable.
Therefore, 3 docks, 5 icons each dock, 2 actions per icon = 30 apps/actions. That is lota space saving right there
The mentioning and screenshots of the widgets few posts up was only to illustrate that LP has amazing and beautiful widgets and maybe they can replace the sense widgets in few months (when more widgets are out).
