'Calculation in progress' indicator

Searching the forum I figured out there’s no an easy way to implement a progress bar in grasshopper at the moment. But is there a way to see if the solution is complete?

Ideally I want some fancy gif to pop up when calculation is on and hide it when the solution is done.

Hello, I’m looking for the same thing. Is it possible to display a pop up window in Rhino when the calculation is done.
Perhaps with “GH_Document.SolutionStart Event” but I dont know how it works.
