Gutterpress 0.11.16: smarter components and a snippet card grid

Released 2026-10-09.

This release is about plugin components: helping authors write them correctly, and letting plugins tell authors when something is off.

Components guide the author

Example snippets. Pick a plugin component, by typing @ at the start of a line or from the snippet picker, and the editor inserts the component's example snippet: snippets/<marker>.md in its extension, or the path the marker names with snippet:.
Variants in autocomplete. Typing @sk lists @skill and one @skill <variant> entry per variant the marker declares.
Content checks. A marker may declare validate(component). It gets a plain description of the content and returns problems, which show in the Problems panel, gutterpress validate and builds, at the right line.
Mistyped variants are reported. @npc-stat wirephreek used to be ignored silently. Now Problems says it is not a variant and suggests the one you meant.
Section markers. A marker declared with section: true behaves exactly like a core @section carrying the marker's classes.

A searchable snippet picker

Snippets now show as cards in a grid, grouped by level: your book, each extension, then core. A search box filters by name and content as you type, level chips and "Components only" narrow it further, and Enter inserts the first match.

Extension versions

Each npm extension on the Features tab has a Version menu. Choosing one installs it the way gutterpress ext add name@version does, and the pin moves only once the new version has downloaded, verified and loaded. A missing or broken copy gets an Install (or Reinstall) button. Book settings → Features is now split into Installed & built-in, Search and Advanced tabs.

Also in this release

The status bar gains a Books button and a regrouped right side, paging is centred in the preview toolbar, the editor fills its pane again, and "Fit to width" no longer scrolls sideways on fractionally scaled displays.
