Changelog
Features Improvements Bug fixes - Added new default Adwaita and Adwaita Dark color schemes - You can now customize the working directory for new tabs. It can be set to persist the last tab's directory, the user's home directory, or an arbitrary location - Closing a tab or a window that still has a running process will now prompt you for confirmation - Black Box now uses the default Adwaita tab style. As consequence, some header bar options, including "Show Borders" have been removed from the preferences window - Added the option to disable terminal bell - Added option to use bright colors for bold text - You can now get a desktop notification when a process completes on an unfocussed tab - Context-aware header bar: the header bar can now have special colors when the active tab is running sudo or ssh - Added open and copy link options to the right-click menu - You can now rename tabs with the new tab right-click menu, or with a new shortcut Shift + Control + R - Added a quick application style switcher to the window menu - Some configuration options have been grouped together in the preferences window - Application title is now bold when there's a single tab open - Performance and bundle size optimizations - Black Box now has more Flatpak permissions to overcome errors reported by users - Fixed an issue that caused terminals not to be destroyed when their tabs were closed - Improved keybinding validation, allowing more valid key combinations to be used - The window title is now centered when there's only one tab - Sixel is now disabled for VTE builds that don't support it.
