Default Disable Border in Editor?

I just started using Zooper and it's pretty great. One question/issue though.

Is it possible to disable the grey border in the widget editor? It obscures the pixels at the edge of the widget when positioning, which makes exact positioning a trial & error affair. Some of us who disable margins on our home screens like to work right up against the edge and the editor's border makes it a little bit inconvenient. It's kind of unnecessary anyways, since you can already change the background color of the editor to contrast at the true edge.

Here is an example of the difference between the editor edge and the screen edge. The widget is against the edge of my screen with no margin.

Sorry about the weird copy/paste link. Apparently I can't imbed images until I have more posts with my account.
