Your Tabs, Version by Version: Session History, Parked Windows and a Calmer Backup

Session history: go back to Tuesday

A saved session changes. You press Update with the tabs you have open now, a Live Session re-saves itself as you work, a scheduled session is refreshed. Until now each of those replaced what was there. With Session history, Nest keeps the previous content as a version for 30 days.

• When a version is written: every time you press Update, and when a Live or scheduled save changes the session. Live and scheduled saves add at most one version an hour; after a day, only the last version of each day is kept. A save that changes nothing is skipped.
• Where you find it: open the session’s ⋯ menu and choose History…. Each row shows when it was saved and how many windows and tabs it held, such as “Tue 09:12 · 2 windows · 24 tabs”.
• Restore as new Session is the default: the old version becomes a session of its own and nothing is overwritten.
• Replace current asks first. The tabs it replaces are kept as a version, so replacing is itself something you can go back from.

Versions are stored in your account with Pro sync, so the list is the same on your other computers. They keep tab addresses, titles and the window layout, they are not part of exports or imports, and they are not in the Vault. If Pro ends, new versions stop being written and the existing ones expire after their 30 days. On the free plan, History… is shown greyed out.

Park idle windows (Pro)

Some windows exist because of a project you started last week. Nobody closes them because closing means deciding. Park idle windows makes the decision reversible: when nothing in a window has been used for 3, 7 or 14 days, Nest saves it as a session named “Parked window” with its date, groups included, and closes it.

• It is off until you choose it. In Account, under Autopilot, pick After 3, 7 or 14 days. Turning it on starts the clock, so old windows are not parked on the spot.
• Undo for ten minutes. A notice with counts tells you what happened. Undo reopens the window and removes the parked session. After that, the session is an ordinary saved one in Backup: open it, pick tabs out of it, rename it.
• It leaves some windows alone: the one you are in, a window with a pinned tab, a tab playing sound or still loading, private windows, sites on your never-touch list, a window a Live Session follows, and your last ordinary window.
• Free accounts see the choice with a Pro label, and it does nothing until Pro is on.

Like every Autopilot rule that closes something, Park writes the tabs down before it closes the first one. If it cannot, nothing closes.

Switch instead of duplicate

Duplicate Autopilot closes exact copies of a page you already have open. Switch instead of duplicate handles the moment before: you click a link, a new tab opens in front of you, and the page is already open in the same window. Nest closes the new tab and takes you to the one you had.

• It acts only on a tab that just opened, within ten seconds, and only when the address matches exactly.
• It never touches pinned or private tabs, sites you excluded, or a copy in another window, because taking you there would pull a different window forward.
• The closed tab is in Closed Tabs like any other close, and the weekly summary, if you turn it on, counts how many times it switched.
• It is free, and off until you turn it on.

A calmer Backup tab

Backup used to open on a long list of tabs from every device. It now opens on what you saved on purpose.

• One line for Autopilot at the top, such as “Autopilot on · saved 3 windows this week”. Tap it for the full card.
• Saved Sessions come first, with Save this window, Save this group and Import in a row. Export, Sync now and tab search moved into the ⋯ menu of that section.
• Open tabs are folded. This device is open; Other devices is collapsed; devices that have not synced for a month or more sit under Older devices. Closed tabs and Vault snapshots are collapsed too, and Nest remembers what you opened.
• Forget hides an old device on your computer at once. With Pro sync, a device that stays silent for 90 days is removed from your account and Nest tells you once. If that device syncs again, it comes back.
• Organize hides empty categories behind one row, “Show 9 empty categories”. Rules and drag targets still see every category.

How to try it

1. Chrome updates extensions on its own; to hurry it, open chrome://extensions, turn on Developer mode and press Update.
2. Open Account and find the Autopilot card. Tick Switch instead of duplicate if you want it, and choose a Park interval if you are on Pro.
3. Open Backup. Press ⋯ on a session and choose History… to see its earlier versions once it has some.

Nothing in this update asks Chrome for a new permission, and nothing needs an account except Pro.
