Icon badges notifications

This project is very promising. Thank you very much for sharing your work, I am loving it!!
Can anybody help me with this?

  1. I was not getting icon badges notifications. I changed settings in Trebuchet and now I get a small blue dot on the icon. Is there anyway that this badge shows the number of notifications pending? would it be possible to change the color of the badge to make it a bit more visible?

  2. Screen mirroring doesn’t work for me. Any idea what could it be? Any app I could install to make it work?
