Looking for alternative application for Gnome Terminal / Console? Try Black Box, a beautiful GTK4 terminal with custom theme and font support.
It’s a free open-source app written in Vala and uses GTK 4, libadwaita, and VTE. Similar to Gnome Console (aka, kgx), it has a good looking user interface that well integrated with GNOME desktop.
The ‘Preferences’ page offers option to change the terminal font as well as text size via Gnome style font selection dialog.
There are 12 built-in themes available for choice. It’s compatible with Tilix terminal color themes. And, it provides the links to download from internet and where to put the theme files.
The terminal by default integrates tabs into header bar, so you have more work space. Though, it also supports for hiding the header bar to focus your job. And, you may move cursor to top-left of the app window to show the floating controls.

- Change blinking cursor from block to ibeam or underline.
- Quickly open links and files by ctrl+clicking file paths and URLs
