Suggestion/Idea: Cli/Terminal only mode

Hello,

I have been thinking of a cli terminal only mode where no gui show up when you want to scan your network. Do you think this is a great idea ?
I will be happy to implement this feature myself, but I need the approbation of a maintainer of this repository before I start working of a PR.
If you think this could be implemented, we need to agree on a flag to launch the app as cli only mode.

I will be happy to hear back from you.
