Describe your feature request below

Hi! I'd like to request support for Black Box terminal, the Fedora repo provides as well as AUR for example both provide it for native installation.

Thank you!

Hello, from some testing with the Fedora package, it doesn't look like Blackbox will integrate properly with BoxBuddy.

Most terminals want to be launched with commands using separate args, e.g.

gnome-terminal -- distrobox enter OpenSUSE

However, this does not work for Blackbox, it instead wants the command as one argument

blackkbox-terminal -c 'distrobox enter OpenSUSE'

Unless there's another flag to use, or the maintainer wants to change the argument passing logic, this won't work with BoxBuddy.
