Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
What's new in 1.13
• New File (⌘N) — create a new markdown document right inside MDViewer and save it later with the system save dialog
• Open Recent — quickly reopen recent files from the File menu or by right-clicking the app icon in the Dock
• Untitled draft fallback — empty new documents no longer lead to a blank, dead-end screen; instead, you get clear actions to edit, open a file, or discard the draft
• Safer unsaved handling — closing the window now correctly asks what to do with unsaved changes
• UI polish — fixed repeated Open File dialogs on rapid clicks and aligned the status bar icons for a cleaner look
Under the hood
• Improved overall stability and performance across editing, file handling, and view transitions
