Sharebox
Share button with green plus icon is off state, and the dark bg one is active state with popup.
There are different post types represented with icons listed vertically, each icon comes with its own colour for itself and as bg to the group like "message type" has orange-ish. The form changes according to selected post type.
I hope you find it handy. I also attached bigger view.
Cheers,
@Oykun
