Fixed table of contents changes sometimes not being saved. Fixed the sidebar's table of contents and thumbnails buttons getting cut off when the sidebar was narrow. Can now make the sidebar narrower to leave more room for documents.

Added support for opening password protected PDFs.

Open multiple PDFs at once, each in its own window. Documents can now open as tabs, respecting your macOS "Prefer tabs when opening documents" setting. Close a single tab with Cmd+W, or the whole window with Cmd+Shift+W. New windows cascade into view and remember their size and position between launches.

Pick your look — System, Light, or Dark — from the toolbar. Dark mode now sports a warmer accent colour.

Sidebar width now persists between documents and across app launches. The sidebar resize divider is thicker, making it easier to grab and drag. More reliable drag 'n' drop of files onto thumbnails sidebar to insert pages. Cmd+Right/Left fully expand/collapse the table of contents tree at the selected item.

Table of contents items created from selected text now link to the selection's location, not the top of the page. Selecting a table of contents item now scrolls to the bookmarked location on the page, not just the page itself. Option+Arrow keys to move, promote, and demote table of contents items, with full undo/redo support. Table of contents sidebar indentation and highlight now match the full sidebar width. Tab key now reliably cycles focus between the table of contents sidebar and the document page.

Text selected in the PDF is now used as the name for new table of contents items. Fixed incorrect menu item names and enable states.

Added printing support. Dropping a PDF onto the app's content area, an empty window, or the dock icon now opens it. Table of contents selection highlight now dims when focus moves away. Increased the indentation of child items in the table of contents for improved visibility. When the table of contents is empty, arrow keys navigate the document without needing to set focus first.

Fixed an issue with the app's window minimising when opening another document via Finder. Fixed the zoom/scale not being correctly applied when changing pages. Fixed an issue with zoom in/out not using the correct scale.

Zoom to 100% now displays the page at its true physical size. Zoom to Fit Page now scales the page to fill the available view area — whichever dimension (width or height) is the limiting factor.

Added support for dropping image and text files to insert pages into PDF document.
