Feature description
I'd like to have commands when I long press icons on launcher that supports it
An example of app shortcuts
I see at this place there are already the two buttons, "Failsafe" and "New session" but it would be great to have custom commands
I imagine this as a folder like ~/.shortcuts and every script here is as a shortcut, exactly like the widget

Reference implementation
I don't know whether other terminal apps have this feature, but it shouldn't be very difficult to implement as there are already the two buttons here, meaning the developers who made this already know how it works. I'd like to make a pull request but I'm poor at Android development and it seems complicated
