The viewer is a three-part IDE: an **activity bar** (left), **document tabs**
(center), and an **inspector** (right).

## Activity bar

Six sections, switchable with ⌘1–⌘6:

| Section | ⌘ | Shows |
| --- | --- | --- |
| **Scenarios** | ⌘1 | scenario files with last-run status |
| **Helpers** | ⌘2 | helper files (read-only) |
| **Collections** | ⌘3 | collections — create / rename / reorder / run |
| **Runs** | ⌘4 | history of every run, filterable by status |
| **Active** | ⌘5 | live, in-progress runs |
| **Variables** | ⌘6 | edit `.env` / `.secrets`, reveal secrets, toggle flags |

At the bottom: a terminal toggle, a theme toggle, and the version.

## Document tabs

Open scenarios, helpers, collections and runs as tabs. ⌘W closes the active tab;
right-click for Close / Close Others / Close All. Tabs and layout persist across
reloads.

## Inspector (right)

Context-aware: during a **live run** it shows Vars / Call stack / Trace /
Breakpoints; for a **failed run** it shows the artifact tabs (screenshot, semantic
DOM, console, trace). See [Inspector & artifacts](/viewer/inspector/).
