Option to stack toasts

[seggewiss]

I would like to contribute an option to stack toasts instead of them being linear on top of each other. Before I waste my time I would like to know if this is something you would approve and be interested in? 😊

An example of what I mean can be found here. Just spawn multiple toasts and see the stack. Once hovered over the stack the stack expands.
