A coding agent runs for minutes. Your next thought arrives in seconds.
There are only two things you can do with that thought today, and both are bad. Interrupt the run and risk dropping a half-formed prompt into a live confirmation gate, or hold it in your head until the agent finishes and hope it survives the wait. It rarely does.
Jellypad exists for the gap between those two. One shortcut opens a panel over whatever you were doing, you leave the thought there, and it waits. The north star was written before a single line of Swift: your thoughts should wait for the agent, not the other way around.
