The editor has four regions. One word first, because it is used
throughout: a **node** is one step in the experience — a scene, a
cover, or a page. They are all nodes because learners walk through
them the same way and the editor counts them together. Where this
article says "node", read "scene" if scenes are all you have made.

## The header

A block across the top of the screen: the section it belongs to, the
title at a readable size, a line of counts, and the controls down the
right — **Preview**, **Publish**, **Share**, **Theme**, **Readiness**,
the two undo arrows, and an overflow menu for duplicate, version
history and delete.

**Readiness** is the one to know about. It lists what is unfinished,
and publishing is refused while any picture has no description — see
[Readiness: what has to be finished before you
publish](/support/articles/readiness-before-you-publish).

**Theme** picks the colours and lettering learners see this experience
in — see [Themes and branding](/support/articles/themes-and-branding).

The counts line says how many **nodes** the experience holds rather
than how many scenes, because a cover and a page are nodes too.

The **"?"** here opens help for whichever panel you are in.

## More room to work in

The expand button, at the top right beside **Preview**, withdraws the
app's own menu and topbar and gives the space to the editor. Nothing
else moves, and the button stays where it was — press it again, or
press **Escape**, to bring them back.

It is not remembered between visits. Full screen is something you do
for a stretch of work rather than a preference, and an editor that
opened with the rest of Panova already hidden would be a worse trade.

## The node rail (left)

**Experience nodes** in order — your scenes, and the covers and pages
that sit among them. Drag to reorder; the order is what learners walk
through, and what "Order the sequence" scrambles. Select one to edit
it. See [Experience nodes: scenes, covers and
pages](/support/articles/experience-nodes-scenes-and-covers).

## The canvas (middle)

The scene itself. Above it sits **Pin tools**: an arrow for selecting,
and a map-pin button that turns pin placing on. With the pin tool on,
each click on the picture places a pin; with it off, clicking does
nothing but clear your selection. Drag a pin to move it. For a 360°
scene, drag to look around; the position you leave it in is not the
learner's starting view unless you set it as such.

Hold **Shift** to select several pins at once — then edit their
context, style or visibility in one go.

## The right panel

Changes with what you have selected:

- **Nothing selected** — the experience's own tabs, described below.
- **A scene selected** — backdrop, projection, title overlay, audio,
  contributions.
- **A pin selected** — its label, blocks, display style and context.

> Four working areas. The middle is the only one a learner ever sees.

## The experience tabs, one line each

A row along the top of the editor, above everything else. The first
five sit together on the left; **Link Manager** and **Experience
Settings** are pushed over to the right-hand end, because they are
tools *for* the experience rather than parts of it.

- **Design** — the working view this article has been describing: the
  node rail, the canvas and the panel beside it. This is where you
  build.
- **Properties** — the experience's name, its icon and colour, and the
  overlay a learner meets before the first scene.
- **Interactivity** — the activities that run across the whole
  experience, and the rules for each. Activities that run on a single
  scene are set on that scene instead.
- **Review** — where learner work lands: what has been handed in, and
  the versions learners built for themselves.
- **Insights** — where learners get stuck, how far they get, and
  whether the experience is reachable for everyone.
- **Link Manager** — every web address anywhere in the experience, and
  whether it still works.
- **Experience Settings** — four sub-tabs of its own:
  - **General** — publishing state, the direct link, how learners move
    between scenes, and the default look of pins.
  - **About** — the short summary a learner reads before starting.
  - **Team** — the colleagues you have named on this one experience.
  - **Danger** — one control: delete this experience. It goes to the
    **Bin** first, so it can be restored.

## Saving

There is no save button — edits are written as you make them, to the
**draft**, and the header tells you when the draft has moved ahead of
the published version.

Because nothing is saved by hand, there is an **Undo**: two arrows in
the header, and **Ctrl+Z**. See [Undo a change in the
editor](/support/articles/undo-a-change-in-the-editor).
