The UserIntercae Object already has functions for creating a messageBox and an inputBox.
It would be very helpful if you could also display an errorMessage/warningMessage in the lower right corner and an infoNote also at the same position. Alternative to that the already existing ui.messageBox() method could be supplemented with an additional third parameter which indicates the type of the message (normal, info, error, warning, ...)
ui.errorMessage("","")

ui.warningMessage("","")

ui.infoNote("1 Kante | Länge ..."):

Would be also cool if somebody can add a new 'Label' for 'API' while creating a post in here (IdeaStation).
