That dark theme looks clean af.
Holy shit dude.

Swiss Knife is a high potential Oxygen Builder Add-on with multiple powerful features, and my favorites are Dark Mode, Faster Top Bar, and Debug Mode, which make this add-on a huge time saver while building websites with Oxygen.

Swiss Knife has established itself as one of my favorites. It has become a must-have plug-in for the Oxygen Builder. Personally, I mostly use the ingenious Font Manager, the Script Manager and the Dark Theme for the editor. It's worth every penny.
