v1.2.0

• Stays on screen while you scroll again, as before 1.1.0: it shows once you scroll down 50 px, no longer waits for the site header to scroll past, and no longer slides away with Deluminator's switch on phones.
• The green glow is back at the end of the post, in light and dark mode, with the original bounce to 1.2 times its size.
