With a swipe of four fingers, I can turn a set of windows into a tiled configuration by "shoving" them where I need to go.
When I press Caps Lock, which I've rebound in Karabiner to F16 and then bound F16+various modifiers to Activate/Hide Application in BTT, I can switch between IntelliJ, Chrome, Figma, Slack, Notion, so fast that I feel like I have 3x as many monitors as I do - which, whether paired with actual monitors or on the road, is absolutely game-changing.
Knowing that I can context-switch immediately and get everything I need on screen, just so, lets me wear a lot more hats than I otherwise could have. There's an argument that I'm able to deliver results at a level as if I had 100 more hours every month!
