Settings
- Auto-scroll to active element — Scroll to selections, including Structure; on by default.
- Scale content to fit the screen (zoom) — Shrink wide previews to fit; off uses actual size/horizontal scrolling. Does not enlarge small previews; on by default.
- Dark Mode — Editor theme.
- Disable Message For Empty SSR Elements — Hide empty server-output messages.
- Show elements ID in the Structure Panel — Display internal IDs.
- Disable Code Editor Line Wrapping — Horizontal code scrolling.
- Prefer TinyMCE For Rich Text — Use TinyMCE where compatible; variable-supporting controls retain their required editor. On by default.
- Include Custom Breakpoints in Breakpoint Dropdowns — Include in compatible threshold controls; individual restrictions remain.
- Disable Custom Unit Dropdown — Disable free-text units while retaining existing values.
- Default Unit Type — px / % / em / rem / vw / vh / svw / svh / auto / custom; default px.
- Remember Last Tab Per Element — Per-element rather than shared tab selection.
