While we don't have an undo button or action, snapshots allow you to undo changes to your schedule by restoring earlier versions. We changed this feature to be more undo-like in November 2024.
In order to access your snapshots,
Click the Last snapshot saved... link at the top of the schedule maker:
This will bring up the snapshots dialog:
autosaves are created after each schedule change
all snapshots are available for 15 minutes so you can undo your most recent changes.
if you're inactive for 15 minutes and then start working on your schedule again, the last version before that 15-minute inactivity is going to be locked in as an autosave snapshot.
up to 10 autosave snapshots are kept in storage. once you reach that number, the oldest autosave will be deleted when a new one is created.
to prevent auto-deletion per the above rules, you can pin an autosave snapshot. you can name your snapshot when you pin it.
additionally, you can create manual snapshots of the current state at the bottom and enter a name for the version.
an autosave is created before each restoration, so you can always roll back to what you had before you restored a snapshot.
Note: if you change the underlying settings of your schedule (number of teams, games, weeks, adding playoffs etc.) this can interfere with a snapshot's ability to be restored. snapshots are mostly meant to serve as backups of your schedule itself, not so much to try entirely different setups. For more extensive experimentation, we recommend copying your schedule.
