Here's a little code snippet I've been using to add a hidden slow motion toggle to my prototypes. It's handy for our devs to be able to toggle slow motion on and off when working on complex animations.
Neat, I didn't know we could just set the delta like that. Nice one :)
By the way, just a quick bonus tip: You can also do Framer.Loop.delta = 1/300 directly in the JS console in your browser (cmd+alt+c in Safari) if you just want to check your transitions without adding any extra code.
