Improved UI for desktop app

[ghost]

Is your feature request related to a problem? Please describe. The BlackHole app has a great UI but only on mobile/small devices. On desktop, the UI is very inefficient does not make use of all the real estate. It has some glaring issues too like not being able to scroll sideways with a mouse although I expect it to be fixed soon.

Describe the solution you'd like A better UI that makes use of the screen real estate while maintaining a consistent design with the other platforms.

Additional context A UI mockup made by me. It isn't the best but again I'm not a UI designer. This is just an idea. I don't expect it to be a real thing.
