Ideas don't arrive at convenient times. The Global Inbox gives you a permanent quick-capture zone — accessible from any board, any view — so you can get the thought out of your head and into TaskBird in under five seconds.
Inbox tasks sit in a dedicated column that you can pin to any board. When you have a moment, triage them: assign a due date, add labels, move to the right list. Until then, they're safe in the inbox and off your mind.
The inbox is especially useful if you're coming from a catch-all notebook or notes app. Everything goes in, then you process it on your own schedule. No guilt about the pile — that's what it's there for.
