Fit Height zoom mode

in 3.7 pre-rel
The new Fit Height zoom mode (View / Zoom menu, command palette CmdZoomFitHeight) scales the page so its height fills the window. You can also use it with -zoom fitheight, the fit height setting value, and DDE zoom -6 (#1714).

New built-in themes

New themes: One Dark, Monokai, Nord, GitHub Dark, Catppuccin Mocha, Tokyo Night, Gruvbox, Night Owl, Ayu and Palenight. Themes can also set their own colors for disabled, hover and edge states. The Darker theme was merged into Charcoal, and settings that still use the old name keep working.

Favorites in a tab, with search and sorting

Favorites can open in a full-window tab (CmdFavoriteShowInTab, “Show Favorites in Tab”), so long names and paths fit. Both the sidebar and the tab have a search box that highlights matches. Favorites can also be sorted by name instead of page number, with SortFavoritesByName or the Sort By Name item in the tree’s context menu (#2277). You can now drag the sidebar wider than half the window.

Bookmarks improvements

The Bookmarks sidebar shows page numbers right-aligned on each entry (turn off with ShowTocPageNumbers = false) (#3288). New context menu items: Collapse Same Level (#1895) and Expand to Level 1/2/3 (#5239). All bookmarks that point to the current page are highlighted (#4642). The search box got better keyboard handling.

Screen reader access to document text

Screen readers (Narrator, NVDA and other UI Automation clients) can now read the text of PDF, XPS and DjVu documents in release builds (#321).

Page size in several units and more page info

Document Properties now shows the page size in cm, mm, inches and pixels (#2186). For FB2 books it also shows the book’s annotation as Subject (#2254). For images, the page-info tip (I) shows the file name, size, resolution and DPI (#4456), and the tip now stays on when you switch tabs or visit the home page (#4454).

Search start remembered as favorite

When you start a search with Ctrl + F, the current page is remembered as the favorite /. You can jump back to it from Favorites or with the $ mode of the command palette (#5726).

Manga mode reverses Left / Right

In manga (right-to-left) mode, the Left / Right arrow keys and horizontal swipes are reversed, so Left goes forward (#3964).

-new-window with several files opens one window

-new-window with several files now opens one new window with a tab for each file, instead of a separate window per file (#5044).

PDF open action and destination zoom

PDFs with an /OpenAction GoTo open at that page the first time you open them (#1631). Bookmark and link destinations now use the zoom the PDF specifies (/Fit, /FitH, /FitV, /XYZ etc.) (#5828).

New advanced settings

PaddingAfterLastPage adds extra scroll room after the last page in continuous view (#411). ShowAnnotationNotification = false turns off the tip shown when hovering over an annotation (#4501). TabWidth is now scaled for DPI, so it works on high-DPI screens (#3850).

Search ignores hyphens at line ends

Search now finds words that are split with a hyphen at the end of a line, or that contain soft hyphens (#1189).

Zoom menu marks custom zoom levels

With custom ZoomLevels, the Zoom menu now shows a mark next to the current level when you zoom with +/- (#5832).
