Reference Sidebar & Site Tree: A collapsible left sidebar in the Source Viewer displays an interactive virtual file system (VFS) tree of all resources referenced in the viewed source file
Viewer Tab Favicon: Added favicon to the Source Code Viewer, Font Viewer, and in-place viewer tabs so they are easily identifiable among open browser tabs.
Improved Download Filenames: Downloaded source files now derive meaningful names from the original page's <title> (formatted as "{title} - {hostname}.html") when the URL path lacks a specific filename, replacing generic download.html names with sanitized, safe titles.
Toolbar Copy Split Button: Added a split-button dropdown in the toolbar allowing one-click copying of the formatted source code (default action), raw unformatted source code, or the source URL, with visual "Copied!" feedback.
Dedicated "View Source" Context Menu: Right-clicking any webpage, frame, link, or selection now offers a "View source with Source Viewer" action in the browser context menu, opening the viewer directly without routing through the browser's native view-source: navigation and completely bypassing redirection flicker.
Configurable Opening Mode: Added an "Open source viewer in" preference allowing users to choose whether to open the viewer in a New tab (default) or Current tab (In-place).
Both the browser toolbar action icon and the new context menu entry respect this setting.
Configurable directly from a new Settings button in the viewer toolbar (via a dedicated modal dialog) and from a standalone Options page opened in a dedicated browser tab.
In-Place Viewer Dismissal: Added a "Close" button to the toolbar when running in-place inside an iframe over an active webpage, allowing users to dismiss the viewer overlay and resume browsing the host page without reloading.

Keyboard Navigation in Code Viewer: Arrow keys (↑, ↓, ←, →) and page keys (PgUp, PgDn) were not scrolling the code viewer on initial load or after clicking into the code due to a focus trap on the non-scrollable root element. Focus is now assigned directly to CodeMirror's scroller, and the browser focus ring is suppressed.
Visual Flicker During Viewer Loading: Eliminated white flashes and intermediate layout/styling transitions when opening source files
