Reader.md v1.1.0

Open individual markdown files — not just folders.

What's new

• Open File… (⌘O) — open a single .md file directly. Add Folder… moved off ⌘O.
• Drag & drop — drop a .md / .markdown / .mdown / .mdx file onto the window to open it (folders still register as roots).
• Default markdown opener — the app now declares itself a Markdown handler, so you can set it as the system default and double-click .md files to open them in Reader.md. Files opened from Finder render straight away.
