    Twilight changes 1.18t

    Twilight is a Zen Browser pre-release that introduces experimental window syncing and per-space session restore. Tabs gain custom icons, drag-and-drop reordering, and rename access for all tabs, plus faster startup and better MacOS Spaces integration.

    Please note that Twilight is a pre-release version of Zen Browser. It may contain bugs and unfinished features.

    If you encounter any issues, please report them on the issues page.

    • Added Merged window syncing! Now, when you open multiple windows of Zen, they will stay in sync with each other. Changes made in one window will automatically reflect in all other open windows. (Experimental, some features such as glance still can't sync yet.)
    • Added Session restore now remembers which space each window was in.
    • Added Tabs can now have custom icons (set via right-click context menu).
    • Added Implemented new tab drag-and-drop system, making it easier to rearrange tabs specially when multiple layers of folders are involved.
    • Added You can now collapse all pinned tabs by clicking on the space name below the essentials.
    • Added Before, only pinned tabs could be renamed; now, any tab can be renamed via right-click context menu or double-clicking the tab title.
    • Added Improved startup time when restoring large sessions.
    • Added New MacOS profiles will now have 'switch to N space' keyboard shortcuts filled by default (control+number).
    • Added Improved native menu bar integration on MacOS (and Windows/Linux if applicable), adding a 'Spaces' menu item for easier access to space-related actions.
    • Added Enabled de-cluttering preference for context menus.
