The Extension Panel

The Extension Panel

Once a project is open, MPX's own icon appears in the activity bar. Its panel has three sections — Project, Module, and Compendium — each collapsible independently.

Project

The project as a whole, rather than its content:

• A summary line (module name, version, system, content language) — click it to open module.json.
• Cover Image / Banner, if set in module.json and the file exists — click to open the image.
• Project Settings — opens .vscode/settings.json, where MPX's project-wide options live (theme, language, measurement units, and more — see Project Settings).
• Translation Overrides, once that file exists — shows how many overrides are set. See Project Settings.
• Compendium total entry count — click to jump to the Compendium section.
• images/ and assets/ as browsable folders, so you don't need to switch to VSCode's own Explorer just to peek inside.

Three buttons sit in this section's title bar: Build Module, Select Project Theme, and Create Translation Overrides File.

Module

The tree of your module's content — pages, groups, maps, and encounters — nested by parent and ordered by rank, then name.

• Click an item to open its file.
• Right-click an item for Delete — moves the file to your OS trash (recoverable), after a confirmation.
• The tree refreshes automatically as files are created, edited, or deleted. A manual Refresh button is also available, alongside Collapse All.

The remaining title bar icons create a new page, group, map reference, or encounter reference — see Creating Module Content for what each one does.

Compendium

Your reusable game content — items, spells, roll tables, and monsters — organized by category, each labeled with its entry count (e.g. "Monsters (3)").

• Click an entry to open its file.
• Right-click for Delete, same as the Module section.
• An entry authored inline in a page (rather than as its own file) appears here too, labeled "inline" — clicking it opens the page and jumps to that block.

The remaining title bar icons create a new monster, spell, item, or roll table — see Managing the Compendium for what each one does.

Next step

With the panel's layout in hand, move on to creating module content — pages, groups, maps, and encounters.
