I am so long time (like 1 years) using ElementaryOS 0.4.1 Loki for this I love here a settings (ACTIVE SIDE! MINIMIZE ACTIVE WINDOW OPTION!!) I loving this, but ElementaryOS 5.0 Juno don't have this can I get this settings in 5.0 Juno else I am installing now 0.4.1 Loki?
sudo apt install software-properties-common sudo add-apt-repository ppa:philip.scott/elementary-tweaks sudo apt install elementary-tweaks
Then open settings and change that option in Tweaks menu.
With Elementary OS's Juno release, this option is conveniently placed in the System Settings.
Navigation: Setting -> Desktop -> Dock
Once at this location, the Dock behaviour controls are Icon Size, Hide When and Pressure Reveal. The Hide When control also has a toggle. If the toggle is set to OFF, the dock stays locked in its position.
