New toasts; Launch settings feedback; Icon bug fixed

Fixes #171 and fixes #168 . Also fixed the toasts to be more apparent (our own "design"), it is yellow and clear. It also shows at the top because while editing the launch code it hovered over my keyboard. Also, I added a random offset so that you see that each key press is a save, otherwise it wasn't clear enough. Plus because of the slight offset you see new toasts clearer anyway. Also the one being shown currently is canceled when a new one appears.

Closes #171.
Closes #168.
