v1.0.5

What's Changed

Features

• File history & tab restoration — ⌘Y opens recent files; tabs reopen on next launch
• Auto-detect external editor — defaults to Cursor / VS Code / Sublime Text if installed
• Smarter Copy as Markdown — partial selections in tables and lists copy just the touched cells / items

Fixes

• Inline math — currency ($5 → $1), link URLs, < / > operators, and $x$$y$ no longer mis-render
• External editor — self-heals if the chosen app is uninstalled
• Right-click image menu — hides non-functional items (Open Image in New Window etc.)

Performance

• Cold launch ~30% faster (1012ms → 726ms on Apple Silicon)
