Managing layouts
A layout is a saved arrangement of the tabs and panels on a form, and you can keep several to switch between as different tasks call for them. Layouts apply to your account only, so the ones you create, switch between, and change are yours alone.
The Layouts menu
The Layouts button in the toolbar above the grid opens a menu listing your saved layouts, with the active one marked. The same menu holds the actions for creating, resetting, importing, and exporting layouts, and for opening the Manage layouts dialog.

Changes to a layout's tabs and panels are saved to it automatically, with no separate save step. To try a new arrangement without changing your current layout, use Save layout as first and rearrange the copy.
The Manage layouts dialog
The Manage layouts dialog lists all of your layouts for the form, where you can download, rename, reorder, and delete them, or create and import new ones. Close the dialog with Done.

Every form has a built-in Default layout that cannot be renamed, deleted, or reordered, so its row shows only the download button. It stays at the top of the list as a clean starting point you can always return to. No other layout can take the name Default, and a name that matches an existing layout is allowed but flagged as possibly confusing.
