Here's one for the icons-in-menus haters on macOS Tahoe:

defaults write -g NSMenuEnableActionImages -bool NO

It even preserves the couple of instances you do want icons, like for window zoom/resize

@stroughtonsmith @gruber for someone who doesn't ever use Terminal, do you just copy and paste that into a terminal window and it should work? a "terminal for dummies" How-To would be appreciated!
@jasonjahnkefilms @gruber the quick answer is yes (and then log out or restart your Mac), but the /right/ answer is you should never paste commands into a Terminal unless you know what they're gonna do!
@stroughtonsmith @jasonjahnkefilms With some commands you need to log out/in for them to take effect, but with this one for menu item icons, you just need to quit/relaunch apps for it to take effect.
