Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
• Pin notes to the top of the list: a new "Pinned" section, per folder.
• Three new guides in the Help menu — Markdown Syntax, Mermaid Syntax and KaTeX Formulas — each showing the syntax next to the rendered result.
• Opening a vault now reopens the last note you were working on.
• Editor: indentation with real tabs (width 4) and vertical indent guides; Tab indents, Shift-Tab outdents.
• Line numbers in Live too; the "copy" button now appears on indented code blocks in Reading as well.
• Modification date and time in the note list, to tell apart notes from the same day.
• More reliable sidebar navigation: selecting and scrolling to the open note now works correctly on launch and when switching vaults, across the folder tree, note list and file explorer.
• Various fixes: Window menu, vault switcher, translations, spacing, and a stray scrollbar in the tabs after switching monitors.
