Blackbox is an Aesthetically Pleasing Terminal for Minimalists Linux Users
Blackbox is a terminal emulator which supports GTK4. The developer created this project so that he could use a decent-looking terminal app on Linux.
So, don’t expect it to have ton of features. It is just a terminal emulator that utilizes GTK4 toolkit and has support for themes.
In other words, it is more about the looks than the features.
