I routinely hide the Dock on my Macbook Air, since it takes up a significant portion of my screen. While I use Alfred most of the time to launch apps and such, I still like to use the Dock; call it a hold over from the last ten years or so.

Sometimes, though, when I move the mouse cursor over to the side of the screen I keep the Dock on (the left, if you’re curious), it pops up even when I don’t want it to.

Then I found this Terminal command which lets me set the time delay between when my cursor hits the edge of my screen and when the Dock actually appears. Now I have the delay period set to a larger number, making it much slower to respond and unhide.

Back in October, we highlighted one of the new features in iOS 5 that allows you to hide previous App Store purchases from your ‘Purchased’ list. It’s great for removing all those apps and games that you may be ashamed of, such as Hello Kitty Parachute Paradise. But what happens if you want to reveal those purchases again?

Well, thankfully it’s easy to unhide them.
