• The current repository URL is https://github.com/thefatheroffire/Obsidian-ppt.

Known limitations

• Animations, transitions, embedded OLE objects, SmartArt, and some formulas are intentionally downgraded
• Very large decks can take longer to parse and repaint during zoom changes

Future enhancements

• Syncing reading position across multiple leaves
• Full-screen presentation mode
• Optional support for .ppt import or slide image export
