Needs rebase and for CI to pass. You can turn on formatting on save in your IDE or run cargo fmt to fix the formatting errors.

I just tested this on windows 11 (which uses windows terminal). The program doesn't appear to actually hide the console window, it remains open.

If I instead use #![windows_subsystem = "windows"] it fully prevents the window from opening - however it then prevents any use from the command line (and ctrl c won't cancel the application, it looks like those signals only work when using the console subsytem), and therefore we won't be able to control if we show the window at launch.

I think we need to investigate a better way that properly works on both the cli and desktop. Maybe we can open a subprocess that does it?

Even though on windows terminal this doesn't work, it works on windows 10 where the old terminal is the default. I'll merge since this improves the windows 10 experience
