Amazing addon! Please let us lock the height of the window. Currently the height dynamically changes based on the listing. I'd like to lock it to be roughly the same height as the default mailing window.

Also changing the static location of the window would be nice. I'll redownload in the future.

The size can be limited by selecting the page size, but there's indeed no way to make it not go below a minimum size. I can see if this is something that's reasonable easy to implement.
