Atom / Nuclide: How do I stop this pop up with the push pin from appearing?

Question

I am not sure when this started but I am now getting this annoying pop up any time I hover over something. Whats it called and how to I prevent it from appearing?

Answer 1

These are Flow type hints. You can disable them by opening the Nuclide Settings page with alt-cmd-, on OS X or alt-ctrl-, elsewhere (separate from the Atom settings, it's searchable so it's easier to find things). Then search for "flow" and uncheck the "Enable Type Hints" box.
