I was building a Session Planner routine.
90-minute focus block. 15-minute break. 60-minute focus block. Perfect.
Then I accidentally deleted the second focus block. And panicked.
I tried to recreate it. Got the duration wrong. Deleted it again. Started over. By the time I finished, I'd wasted 10 minutes just trying to rebuild what I had.
Then I discovered the undo button.
Session Planner is a drag-and-drop interface. You build sequences of focus and break blocks. Reorder them. Adjust durations. Delete blocks. Add new ones.
It's flexible. But flexibility creates mistakes.
You delete the wrong block. You drag something to the wrong position. You change a duration and immediately regret it.
Without undo, you're stuck. You have to rebuild manually. And that friction makes you less likely to experiment.
With undo, you just hit Ctrl+Z. The mistake disappears. And you keep building.
I experiment more now.
I'll try a 4-block routine. Hate it. Undo. Try a 3-block routine. Better. Tweak the durations. Undo if it feels wrong.
The undo button removes the fear of making mistakes. So I iterate faster.
And the routines I build are better — because I'm not afraid to try things and throw them away.
Undo/redo isn't just a convenience feature. It's a creativity feature.
It lets you experiment without consequences. Try things. Break things. Fix things.
And that freedom to iterate is what makes the Session Planner actually useful instead of just another rigid tool.
Small features matter. Undo is one of them.
