Code Annotator

Highlight code, add annotations, and collect them as structured markdown.

Features

Annotate code -- Select any code and attach a free-text annotation via a quick input box.
Gutter icons and highlights -- Annotated lines show a gutter icon and a configurable background highlight color.
Edit and delete annotations -- Right-click on an annotated line to edit or delete the annotation. Overlapping annotations prompt a quick pick to choose.
Collect as markdown -- Gather all annotations into a structured markdown document, grouped by file, and copy it to the clipboard. Annotations are cleared after collection.
Collection history -- Every collection is saved as a snapshot. Browse and re-copy past collections from the history.
Configurable colors -- Customize the highlight background color and gutter icon color through VS Code settings.
Status bar -- See the current annotation count in the status bar. Click it to collect.
