Multiple vizinfo.InfoPanel panels on a canvas?

[Seadna]

Hi folks,

Is it possible to have multiple vizinfo panels on a canvas? When I try this all controls except the text disappear from my original vizinfo.

I have a vizinfo.infopanel with drop-downs and buttons for loading models and point clouds. When i load a model it loads asynchronously, but there is no indication to the user that something is loading so they tend to click the button multiple times. Could somebody provide an example of adding a loading message to the canvas when i load a model?
