The Code tab shows the code in your space, in two sections picked from the sidebar, each with its number of blocks:

• Space Lua: every space-lua block, in the order SilverBullet loads them, and how loading each one went.
• Space Style: every space-style block, in the order they're applied, and how many CSS rules the browser parsed from each.

${widgets.commandButton("Workbench: Scripts")} and ${widgets.commandButton("Workbench: Styles")} open the Workbench on either section. In a narrow dock, the sidebar becomes a picker above the section.
