How it works

The manager page with the window merge area and select-all checkboxes
The manager page: other windows are listed with select-all checkboxes in the merge area.

Merging windows into one

  1. Open the full manager page from the popup.
  2. The window area lists your other normal windows. Select the ones to absorb , checkboxes with a select-all default.
  3. Confirm the merge: the selected windows' tabs move into your current window and settle into their site groups.

Splitting tabs into a new window

  1. Select tabs by title in the manager (or ⌘/Ctrl-click in the tree).
  2. Move the selection into a new window; the rest stays behind untouched.

Free vs Pro, and the safety rails

  • Dragging a single tab into another window is free , that's Chrome's own gesture, and 叠页 keeps the tab grouped correctly when it lands.
  • Bulk merge and bulk split are Pro (US$5.99 one-time, activation code verified locally).
  • Excluded by design: incognito windows and app windows (e.g. PWA windows) are never touched, and your pinned tabs keep their pinned position across moves.
  • Best effort, non-transactional: a batch move is not atomic , if a rare page refuses to move, it simply stays in its original window and the rest completes.

The built-in alternative

Chrome offers no native “merge windows” command: the manual path is dragging tabs one by one between windows, or closing a window and reopening its tabs from history. Single-purpose merge extensions exist too , they move the tabs and stop there. The difference you're paying for here is the second half of the job: after the merge, every tab is already in the right site group, and the result can be saved as a workspace in the same breath.
