Feature Overview

Core Features

Mark::Blocks is built around three things — writing, previewing, output — keeping Metro’s restraint and focus.

Markdown Writing

The input pane is based on RichEditBox and provides:

• Smooth plain-text input.
• Full Undo / Redo support.
• Ctrl + F to find and jump quickly.

Markdown Preview

The preview pane is rendered by an IE11 WebView, using IE11’s text-justify to keep long text neatly justified. The preview supports:

• Code block highlighting (highlight.js, atom-one-min light / dark).
• Math formulas (KaTeX 0.11.1).
• Diagrams (Mermaid 7; Gantt charts unavailable for now).

Export HTML

Export the current document as a standalone HTML file with full styling in one click, ready for offline distribution.

Highlights

#	Feature	Description
01	Tile home	Recent files shown as Metro tiles on the home screen.
02	Metro tabs	File tabs with smooth transitions (room for optimization remains).
03	Split View	Windows-exclusive write / preview split screen.
04	Sync scroll	Scrolling the RichEditBox syncs; scrolling the WebView is independent.
05	Immersive mode	Windows Phone exclusive; hides the file tabs.
06	Three preview themes	Gray #1d1d1d, AMOLED Black, Tokyo Night.
07	Autosave	Toggleable, with selectable frequency.
08	Accent color	Follow the system or the default cyan.

Preview Backgrounds

The preview WebView supports three backgrounds for different writing scenarios and OLED screens:

• Gray #1d1d1d: classic dark gray, easy on the eyes for long reads.
• AMOLED Black #000000: pure black, saves power on OLED devices.
• Tokyo Night: retro night palette with strong atmosphere.
