Stretch a task and watch the plan reshuffle itself
A task runs a few days long, and normally that means an afternoon of updating every date downstream by hand. On the timeline you drag one edge and everything waiting on it slides forward on its own.

The design is going to take three more days. It happens, it is nobody’s fault, and it is also the moment your stomach drops a little, because you know what comes next. The build was scheduled off the old finish date. So was the review. So was the launch. One task slipped, and now half the plan is quietly wrong, and fixing it means opening each downstream task and pushing its dates by hand until you lose track of which ones you already did.
That is the tax on changing your mind, and it is why plans go stale. Not because people stop planning, but because keeping the plan honest costs more than most weeks can spare. So the plan drifts from reality, and after a while nobody trusts the dates on it, which means the plan has quietly stopped being a plan.
On the timeline, changing your mind is one gesture. Grab the right edge of the design task and drag it three days longer. As you drag, everything that depends on it moves. The build slides forward to stay behind the design. The review slides to stay behind the build. The launch follows. You are not updating a plan, you are watching it rearrange itself to stay true.
The cascade
The rule underneath it is simple and strict: a blocker is never allowed to end after the thing it blocks begins. So when you stretch one task into another one’s space, the software pushes the dependent forward just enough to keep that promise, then does the same for whatever depends on that, all the way down the chain. You move one card. The knock on effects move themselves.
The view keeps up
If the drag runs past the edge of the screen, the timeline scrolls with you, so you are never dragging blind into the void. And when the dust settles and you want the plan pulled tight again, one button, Recompact, closes the gaps and snaps every task back against the thing it was waiting on.
A plan that maintains itself is a plan people keep looking at.
The best part is the part you stop doing
Run the slip again. The design takes three more days, you drag one edge, and the rest of the plan catches up in a second. No afternoon of hand editing, no dates left half updated, no standup where two people are working from different versions of the truth.
This is the whole reason we built the interaction the way we did. A plan is only worth keeping if keeping it is nearly free. Make the change once, let the timeline carry the consequences, and get back to the actual work.
