The menu items describe the change they will undo or redo. ### Rename Change the name of your project. This is the title shown in the Projects list and at the top of the editor. ### Duplicate Create a copy of the entire project, including all blocks and parameter values. If the project has variations, a checkbox lets you include them in the copy — otherwise they can be regenerated later. ### Preview layout Control how the preview renders on the left side of the editor: * **Responsive** (default) — the preview adapts to the width of your editor window, giving you a realistic sense of how the email will look. * **Desktop** — fixed 1280px-wide preview. * **Tablet** — fixed 800px-wide preview. * **Mobile** — fixed 375px-wide preview. When a fixed breakpoint is wider than your window, a **View full size** toggle expands the preview to its true pixel size. **Cycle layouts** (Cmd+Shift+F, or Ctrl+Shift+F on Windows) steps through the breakpoints. ### Above the fold Overlay dashed guides showing the approximate fold in popular email clients (or browser sizes, for landing pages) — a rough gut-check for what recipients see before scrolling. Toggle with Ctrl+F. See the [editor interface](/editor/editor-interface) for details. ### Color scheme Switch the preview between **Light** and **Dark** to see how your email renders in clients that support dark mode. **System** (the default) follows your OS preference. ### Disable overlays Turn off the block selection overlays and hover indicators on the preview (Ctrl+O). This lets you click on elements in the rendered preview directly — useful when you want a clean view without any editor UI on top. ### Private Hide this project from your team in the Projects area. Only you (and admins) can see a private project. ### Lock Prevent the project's content from being edited. This is useful when a project is out for review or has been finalized — comments can still be added, but no one can accidentally change the content. Toggle the lock off when you need to make changes again. ### Export project Download the project as a `.project` file that can be imported into another team. ### Import project Replace this project's contents with an uploaded `.project` file, keeping its current library. A version of the current state is saved first so you can restore it later. ### Delete Permanently delete the project. This removes it from the Projects list. Deleting a project cannot be undone. Make sure you have exported or backed up anything you need before deleting. ## The Options tab The **Options** tab in the sidebar holds content-level settings. ### Email options For email projects, the tab is titled **Email options** and includes: * **Subject** — the email's subject line. * **Preheader** — the preview text shown after the subject in most inboxes. * **Tracking** — click to open the UTM parameters dialog, where you can set Source, Medium, and Campaign values. When enabled, UTM parameters are added to all links in the email, and per-link Content and Term fields become available in the [Edit link dialog](/editor/working-with-blocks). Landing page projects don't have a subject, preheader, or tracking section. ### Theme If your library exposes project-wide theme parameters (colors, fonts, and so on), they appear here under a **Theme** heading. ### Versions Click **View history** to browse and restore previous versions of the project. Version history requires the Team plan — on other plans this cell reads **Upgrade to view history**.

Click it for library actions: * **Change library** — switch to a different library without losing your changes. Your blocks are matched up by name where possible. * **Change version** — pin the project to a specific version of the library, or track the latest draft. * **Update** — pull in the latest library changes. This item only appears when an update is available; a blue **Update available** badge shows on the library cell and a notification dot appears on the Options tab itself so you don't miss it. * **View library** — open the library in a new tab (shown if you have library permissions).
