Each Email block owns its own design. The first time you click Design email in the block, Sprwt creates a template titled with the flow number, flow name, trigger, and step number immediately followed by the step's name – for example #12 Welcome Series[user_create] - #45Welcome (note there's no space before the step name, so titles can look slightly squished) – and opens the designer; later clicks reopen the same design. In the designer the Settings Title field is locked (read-only) and the top bar shows a Back to Flow link. These designs are not listed on the Templates page unless you switch on the Save as Template toggle in the top bar, and they are permanently deleted together with the flow (which must first be turned Off before it can be deleted). Flow designs offer the Shortkeys personalisation button and trigger-specific modules matching the flow's trigger (e.g. a Trigger: Abandoned Cart module only appears in an Abandoned Cart flow's design). While the flow is On (active), its designs cannot be opened for editing – you're redirected away until it's turned off.
