Hello, this is a very nice extension the birbs are beautiful. It would be great if we could get some more green birds.

Furthermore, I noticed 2 things, A: The birbs duplicate when there are multiple tabs in view which seems to allow people to multiply the chance they get feathers. B: changes to birbs do not sync up automatically rquiring a refresh to the page.

Although I am sure these were not intended features it is pretty cool as you can have different species of birbs for separate tabs, and you can have multiple birbs in view at once when multiple tabs are in view.
