Added a customizable global shortcut that opens a dedicated always-on-top host switcher, even when the main DisplayMux window is minimized or hidden.
The host switcher supports mouse selection, Tab, Shift+Tab, Up and Down navigation, Enter to confirm, and Escape to close.
Windows and macOS display Ctrl, Windows, Command, and Option keys according to each platform's conventions.
Shortcut safety
DisplayMux attempts to register a shortcut immediately after recording it to detect operating-system-level conflicts.
The shortcut is checked again when settings are saved. If registration fails, the previous working shortcut remains active.
Common application shortcuts such as Ctrl+W and Ctrl+S are rejected to avoid conflicts with browsers and other frequently used software.
Windows shortcuts must include Ctrl, while macOS shortcuts must include Command. Additional modifiers are limited to reduce accidental activation.
Release History improvements
Fixed GitHub Release links in Help so they open correctly in the system browser.
Release History now synchronizes published GitHub Releases automatically and displays the newest version first.
Built-in release information remains available when GitHub cannot be reached.
Compatibility
Global shortcuts and the host switcher support Windows 10/11 and macOS 12 or later.
Existing settings are migrated automatically. The global shortcut remains disabled by default until the user enables it.
Known limitations
Application-local shortcuts are not always registered as operating-system Global Hotkeys. DisplayMux blocks common combinations, but cannot maintain a complete list of shortcuts used internally by every third-party application.
The macOS DMG is ad-hoc signed but not notarized with an Apple Developer ID, so Gatekeeper may require manual approval.
Some MST, DisplayLink, and Silicon Motion docks do not forward DDC/CI. Software cannot restore control signals that the hardware does not expose.
