I’m a pretty heavy dock user on OS X. I have my Applications, Documents, and Download folders pinned to the right side of the dock. Though I am an avid user of keyboard launchers, I like being able to scroll through a big list of my apps. (Launchpad has made a bit of this moot.)

Over at iMore, Peter Cohen has a tip that can help keep just your most used apps and documents on your dock. Making it easier to quickly access things you work with everyday, or just those you need for your current projects.

First, you’ll need to open to open Terminal and enter the following command:
defaults write com.apple.dock persistent-others -array-add '{"tile-data" = {"list-type" = 1;}; "tile-type" = "recents-tile";}'; killall Dock

Once the dock relaunches you will have a new item on the right side of your dock that has your ten most recently used applications. You can right-click the icon to select either Documents, Servers, Volumes, or Items. The last is the items in your Finder sidebar you most click on. For each one you’d like in your dock, just rerun the command and adjust the new stack.
