Switch between instances of apps in full screen?
A bonus method if you want to do this entirely with trackpad instead: I forgot to mention that HyperSwitch also adds this functionality into the mac's built in CMD+Tab app switcher.



You need to enable the setting in HyperSwitch to display window previews on the app switcher.



Again, using BetterTouchTool, I used a trackpad gesture to trigger the application switcher. This BetterTouchTool gesture makes the switcher stay open until you click on something, so you can switch windows entirely with trackpad.
