Minimal Markdown editor with optional encryption.

Features

• Tabbed editing (new / open / close, dirty stars)
• Markdown syntax highlighting
• Live HTML preview pane (Ctrl+Shift+P)
• Find & Replace (Ctrl+F / Ctrl+H): match case, whole word, regex, in selection, in highlighted zones only

Requirements
