Zenreader

New Features

• Highlight Equations and convert them to LaTeX.
• Added Equation Highlighting mode (pick the f(x) highlighting button from the Reader Toolbar).
• Once an equation is highlighted from a PDF document, the image is sent to Mathpix OCR which returns the detected LaTeX. The equation highlight appears in the highlight panel.
•  The Equation highlight can be exported or used within an Outline.
• If the LaTeX code is incorrect, you may amend it directly by editing the original highlight text (and revert back if needed).
• This feature requires you to create a Mathpix OCR account with API Credentials ($1 fees) and to provide Zenreader with your API keys (instructions to do this can be accessed from the Preferences screen → Integrations page).
•  The feature is for Premium accounts only.

Other Changes

• Added project count label and scrollbar in the projects list view.
• Updated the tooltip text for the icons on the outliner cards.
•  When exporting an Outliner the notes of an Image card will appear on the same place as in the Outliner (below the image).

Deprecated Features

• Temporarily disabled the code that checks for duplicates during the import of bibliographic references: the code for duplicate detection is currently very slow and an immediate performance fix was not found. This will be re-introduced in a future version, pending a re-development of the duplicate matching algorithm. With this feature enabled, a file of 3000 bibliographic references could take upwards of 20 minutes to be imported in Zenreader.

Bug Fixes

•  Pasting text from clipboard (ctrl+v or CMD+v) on an outline card was not working.
• Exporting an Outline to Markdown (.md) would freeze when one of the Outline cards had some text in the additional notes section.
• The BibTeX file parser would not proceed with importing .bib libraries that contained comments and/or BibTeX field values that were wrapped with curly brackets. The file parser was re-written using a pattern-matching approach.
• Image and OCR Highlighting was not respecting the limits placed on free accounts.
• Fixed a crash caused by Manually importing a BibTeX citation entry. The crash occurred when the pasted text included the entry with a duplicate entry key.
