Creating A Stack That Shows Recently Used Applications etc In The Dock?
Yes, it is possible using the following Terminal command:

defaults write com.apple.dock persistent-others -array-add '{ "tile-data" = { "list-type" = 1; }; "tile-type" = "recents-tile"; }' &amp;&amp; killall -HUP Dock




This adds a stack to the right end of the Dock (before the Trash) that lists your recently-used apps.



Upon right-clicking on the stack, you can choose from multiple recents lists, and change the style of the list, as well as remove it from the Dock. Running the above command multiple times will add multiple stacks to the Dock, which you can customise individually.
