macOS Terminal - Dock tweaks

[Snakel3ite]

Recent Stack > Description: Display one of the following: Recent Applications, Recent Documents, Recent Servers, Favorite Volumes, or Favorite Items.

Code:

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

After [Return] type: killall Dock

Another cool one,
Mouse-Over effect > Description: Highlights icons with the mouse hovering in grid mode (Stacks only)

defaults write com.apple.dock mouse-over-hilte-stack -boolean YES

After [Return] type: killall Dock

If you want it off type in change YES to NO

I got this script/code from Macworld.com but originally I read in April 2008 edition.
