Kiwi,
Thanks for the link. As to your questions:
1) The "Show Faces" option only works in the "Standard" layout mode. In the box or button count views, it will not display faces. That's simply how Facebook works, and not something we can get around.
2) The send button dialog opened to the left for me. I opened it in a browser window that would have been too small for it to open to the right, and Facebook automatically opened it to the left. I then made the browser much, much wider (so there was a lot of white-space on the right of your page), reloaded the page (important for Facebook to recalculate the width of your window, and when I clicked again, it properly opened to the right.
I've attached a picture of it opening to the left. Can you tell me what you're seeing that's different, and what browser you're using to test? We used Chrome.
Hope that helps,
Alex
