Flexibility with toast location
Some apps would look better if the toasts were shown at the top. For example, Music has this: when a toast is shown, it overlays the player bar, which is at the bottom. Here is a screenshot of a different app below. The way the toast's text is aligned, it jars with the alignment of the red Shred button, and also keeps the user from clicking it [the Shred All button]. In Music, it temporarily disables the user from interaction with the player bar.
