One more reason to get rid of the dock: when you’re working on multiple monitors and you hold Cmd+Tab to switch between apps and happen to have your mouse over the dock, it will move the app list modal onto that monitor. Grrrr.
Looks like if you increase the time delay that won’t happen. It’s been bugging me for age, so props for that!
Also, if you ever need to pull up a dock (for e.g. a minimized window), you can use Cmd+Alt+D to unhide/hide it.
