Notebooks for Mac 2.2 is a major update and includes many new features and improvements.

## Recognize Text in Images and PDF Documents (macOS 10.15)

• The option is available from the ••• menu of images and PDF documents.
• The result is a default document containing recognized text and a link to the original.
• Notebooks saves the recognized text in the document’s info, too.

## Search and Filter

• Search and  highlighted search hits in PDF documents.
• Improved search performance in plain text and formatted documents.
• Cleaner layout of search options.
• The search field contains a pulldown menu with previous search terms.
• The Filter is available for the list of context tags and all other smart books, too.
• To switch from filter to search, type return, even if you select a recent search term.

## Document List

• Editable documents use the thumbnail of first embedded image as icon.
• Document thumbnails load much faster.
• The list’s header contains a Back (<) button to quickly bring you back to the containing book. You can also use the keyboard shortcut ‍⌘↑ .
• Rearranged swipe actions to avoid accidental deletion of books or documents.
• Section headers show numbers of books and documents in 2-column mode.

## Contexts

• In 3-column mode, books assigned to a selected context tag appear in the list along with the documents. This makes them easier to detect.
• Use the filter to quickly find a specific tag in a long list.
• You can select multiple contexts in the outline for an AND combined list of documents which belong to all selected contexts.

## Sharing From Other Apps

• When an app provides text, images and links, Notebooks now tries to save one document combining all these elements.
• Importing PDF and other generic document types works more reliably.

## Other Relevant Changes

### Formatted Documents

• When using the file selector from camera button, Notebooks now inserts all selected images as expected.
• Improved layout of the formatting toolbar.
• Fix bug that a single quote (‘) refused to appear at end of document with insert closing characters enabled.

### Markdown

• Correctly detect {{TOC}} tag and replace it with table of contents.
• Simplify image links and make them compatible for MultiMarkdown and Discount.
• ⌘U inserts the underline tags for the selected text rather than underlining the whole document.
• Take better care of MathJax inlineMath and displayMath definitions, so it is no longer necessary to add extra spaces between brackets.

### Document Themes

• Basic Theme: Use color variable for checkboxes, so they can easily adjust to theme (--checkbox-color:)
• Default Theme: Adjusted display of code
• Default Theme: Fix bug that the first line of code was indented by 1 character (<pre><code>)
• Scientific Theme: Update MathJax definition to also accept \$\$(not just )

• If a link’s target cannot be found, Notebooks looks for an alternative even if the link has no file extension.
• Apart from looking at the exact name, partial name and even checking the contents of editable documents, Notebooks now looks for targets by removing spaces from the given link. So a link to “Getting Started” would yield “gettingstarted.txt”, for example.

### Misc

• New option to turn off live word count; toggle by clicking the green/gray button in the bottom right corner of the window, or from the View menu.
• There is a new setting to control whether Notebooks automatically cleans up embedded images (attachments) which are no longer referenced. This option is on by default.
• You can select a new Notebooks Home by dropping a folder onto the Notebooks icon.
• Documents in a separate windows now show an icon in the window title. This allows you to grab and drag that icon if you want to move these documents to another location.
• Renaming an item by changing upper/lowercase no longer issues a warning.
• If you drop a document from Finder or another app into a Notebooks document while the green (+) icon is visible, Notebooks now copies that document to the hidden NBImages book (the place for attachments) and displays that document inline. If the document cannot be displayed, Notebooks adds a link to the document. (Previously, this was the case for images and PDF documents only.)
• eBook and Compile
• Accept bookmarks (.webloc) and include their URL in result.
• Add individual images to eBook.
• When calling any of these actions without active selection (in smart books especially), books are included as well.
• Print to Notebooks: to install, use Notebooks > Install Add-ons > Save PDF to Notebooks. This adds a new entry to the macOS print dialog’s PDF menu and saves a PDF into Notebooks‘ default inbox (or at the top level).
• Use ⇧⌘H to jump to Notebooks‘ top level.
• Added Duplicate as Fountain for documents containing Fountain markup.
