Disable "node has been created." message in the popup

Hi Tao, thanks very much for this module, got it working in notime!!

Now to get things real slick I want to disable the "node has been created." message which pops up every time after I add a node through a popup.

Is this possible?

Also one other small thing: maybe it will be cool to add a "do not place popup-square next to popup items" checkbox in the admin. I used a vey big + sign to add nodes for example and it gets a little ugly with the square added..

Greetings Bas
