Why do all other windows minimize when I open a window from the dock? Clicking an app icon from the dock causes all other windows onscreen to minimize. Is this intended? Is there a way to configure it so selected app's most recent window gets placed on top without minimizing the other windows?

iMac Pro 2017 on Mojave 10.14.3

I'm running:
Karabiner
SensibleSideButtons
Snap
TinkerTool

Using:
USB Mouse and Keyboard
Try this in Terminal/commandline:

defaults write com.apple.dock single-app -bool false; killall Dock


My hunch is that you accidentially changed this setting in TinkerTool.
