-Sidebar file annotations (DSH 0.1.5-rc.2): select plain text, Markdown, or code in a workspace file preview and use the same annotate, save, and Enter-to-send flow. The editor and model-facing quote include the file path. After reloading and reopening the original file, its markers are restored; identical passages in different files remain separate. PDF, images, and HTML inside iframes are not covered.
