A local Markdown notebook with true WYSIWYG editing, light and dark themes, a five-level folder tree, H1-H5 outline, 297 language syntaxes, Mermaid diagrams, todo lists, KaTeX formulas, full-text search and Markdown/HTML/image export. The Agent tool preview_file opens a single Markdown/text file (by absolute path, no directory grant needed) as a read-only preview; the user clicks Edit to modify it and edits save back automatically (single-file mode, no document list).

Persistent workspace goals, task evidence, and host-owned completion audits for PI-Desktop.

A deep blue-teal global theme tuned to a measured reference: surfaces lifted from #0F1B26 to #223648, hierarchy carried by 1px #2A4054 hairlines rather than glow, a solid #1B4F53 selection state, and a four-step text scale that takes body prose from 17:1 down to 11:1. Styling only — no features.

A warm parchment global theme: cream paper background with a faint grid, ink-colored user bubbles, paper assistant cards, and monospace meta lines. No features beyond styling.

Markdown desktop sticky notes with multiple-note management, live preview, task checkboxes, text highlights and a recycle bin.

Capture clipboard text while PI-Desktop runs, keep 30 days of history, restore any entry with one click.

Browse, view and edit the open project in the right work panel: a full directory tree with per-file-type icons, syntax-highlighted editing, a Markdown preview, image and media viewing, CSV/JSON structured views, read-only SQLite browsing with a SQL query box, a context menu for creating and renaming, and filename search.

PI-Desktop log viewer for huge files: streamed paging with virtual scroll, tail follow, search highlight, text/level filter, pinned lines, and multi-file tabs.

A paper-like multi-line calculator: evaluate as you type, keep a draft history, add notes to each line, copy results or export the sheet as an image, with local draft management and dark mode.
