oh okay that makes sense. I was wondering if there was an easy way to add a fourth switch onto the end of a 3 gang box and this option definitely strikes a good balance between acceptable looks and minimal work required.

Maybe it’s just my OCD but why is the switch on the left so far forward? Maybe you need to remove some spacers or push the wiring behind it back further so it can be screwed in further? Maybe the photo is just poor timing or maybe you’re just a monster and you like it this way?
