Markpad v2.7.0

New Features

• Preview width is configurable: a setting, a shortcut pair to widen/narrow, and the preference persists (#346, #347, #348, #349)
  
• Editor toolbar : new icons and a show/hide toggle (#282)
  
• Window tags and pinned sessions rebuilt (#280)
  
• Moving tabs between windows rebuilt (#279)
• macOS settings menu (#339)
  
• Floating table-of-contents toggle (#331)
  

Documents

• A file over 50 KB opened as a truncated preview, and saving wrote that preview back over the whole document (#374)
• A non-UTF-8 file opened as mojibake, and auto-save wrote the mojibake over the original 1.5 s later (#379)
• Dropping two images with the same name in the same second silently replaced the first while the document still linked to it (#383)
• A read failure during session restore evicted the tab and saved the trimmed list, so an unplugged drive lost the tab permanently (#401)
• Re-opening a file that was already open with unsaved edits discarded them, and cleared the dirty flag so nothing said so (#412)
• Two tabs could hold one path with two auto-save timers writing over each other (#413, #416)
• A tab moved between windows could end up open in both, each copy with its own auto-save timer writing over the other (#366).
• Pressing ⌘S while an auto-save was mid-write could leave the older text on disk (#436, #438).
• Quitting with two tagged windows could lose one window's pinned tags (#424).
• A stale preview render could overwrite a newer one (#254), and an interrupted session restore left the app unable to recover (#260).

Security

• Exported HTML skipped the sanitizer entirely (#376)
• The preview never used the shared sanitize policy, so a document's <style> reached the app's own UI — reproduced hiding the title bar and fetching a remote beacon (#384)
• A link could read as http://… everywhere the user can see it and open a local file instead (#415)
• Imported VS Code theme colours are validated before being injected as CSS (#362), and imported theme slugs are normalized (#301)
• Theme and image file paths are constrained to their directories (#249, #270)
• File IO, decoding and Markdown boundaries hardened on the Rust side (#371)

Export and printing

• Exported HTML now contains rendered math, syntax highlighting and Mermaid diagrams instead of raw source (#411)
  
• Exported HTML carries the theme, and no longer cuts collapsed sections out of the document (#382)
• PDF exports are readable in every theme; diagrams no longer come out dark-on-dark (#359)
  
• A PDF exported from edit mode is no longer blank (#407)
• Local images are inlined on Windows (#363)
• Find highlights no longer print, and collapsed matches are revealed (#377)
• Print layout: native controls, full page width, and tighter content rhythm (#329, #333)
• The export menu is no longer greyed out for an unsaved document you're editing (#441)

Editor and preview

• Task checkboxes work in the preview, and the change is written back to the file (#345, #352)
• Three separate LaTeX reports turned out to be one bug : _{1} becoming italics, \\ being eaten so a multi-row aligned collapses, \% being eaten so KaTeX treats the rest of the line as a comment. All three are comrak applying Markdown inline rules inside math delimiters; fixed by masking the span before parsing rather than patching one character at a time (#351, #402; closes #174 / #177 / #197)
• Escaped dollars stay escaped, and $$…$$ inside a paragraph renders (#422)
• The editor context menu is fully localized and follows a language change (#381)
• URLs pasted inside code blocks are no longer turned into links (#381)
• Scroll position returns to the block you left, not to a percentage (#420)
• Heading folds are per-document, and are cleared when a tab follows a link to a different file (#425, #448)
• A leading --- no longer swallows the paragraph after it (#375)
• Copy Reference produces a link Markpad can actually follow (#403)
• Preview works without saving first (#421)
• ToC jumps use heading source position (#335)
• Editor options and keyboard shortcuts now do what their labels claim (#369)
• Saving works from reading mode (#365)
• "Save image as" works for local images, and says so honestly for remote ones (#408)
• A relative link to a non-Markdown file resolves against the document instead of the app (#409, #415)
• Copy Reference produces a link Markpad can follow (#380), and "open the exported file" had never worked because the opener plugin had no path scope (#403)
• Live Mode watched the wrong file after a tab switch (#296)
• YouTube embeds open externally instead of failing in place (#338)
• Settings: the modal stays draggable (#312), collapsed toolbar sections are remembered (#286), and every setting syncs across windows instead of the last window overwriting the rest (#370)
• Recent files are merged across windows instead of overwritten (#405)
• The auto-save failure toast no longer repeats (#406)
• A malformed UTF-8 code fence crashed the renderer (#265)
• Window titles update natively (#288); a window created at startup is reused instead of a second one appearing (#318)

Windows

• "Move to New Window" froze the app. create_transfer_window built the window synchronously, and on Windows that deadlocks. WebView2 needs the main thread free to pump messages while the window is created (#360)
• Right-clicking a tab twice opened the document menu the second time, because the first menu's full-viewport overlay swallowed the click and only called preventDefault() (#360)
• Install failed outright when the Desktop or Start Menu folder did not exist — this is the cause of the OS Error 3 reports (#400)
• Uninstall could terminate unrelated processes with the same name (#358)
• Install and uninstall are recoverable if interrupted (#364)
• Markpad no longer registers itself for plain text files (#302)
• The Install button stays reachable at large system text sizes (#428)

macOS

• PDF export did not work at all (#287)
• Opening several documents at once from Finder kept only one of them (#298, #300)
• The editor paste menu was missing (#266)

Performance

• Startup JavaScript down 81 % : Monaco now loads when you open the editor rather than before the first paint. First paint went from 4770 KB to 904 KB; entering edit mode costs ~330 ms once per window (#423)
• Mermaid-heavy documents ~12× faster to type in; diagrams are no longer redrawn on every keystroke (2185 ms → 189 ms on a 20-diagram document) (#419)
