Hmm, I was just browsing and I just now noticed that you can re-size the text box to a size of your desire and I was wondering something @Hawkee - could you make the text box overlap the right panels? As it stands it displays under it and you can't see that portion of the text box. :P I'm assuming it's intended to overlap them all, possibly something you missed, perhaps?

Edit: It overlaps the right panels further on down the page, just not the profile panel or the Facebook plug.. Screen: http://puu.sh/1nXsT

Edit #2: Further inspection, it seems to just be the initial "Status Update" text box that's doing it. Screen: http://puu.sh/1nXxJ

Edit #3: It's the same with the Image Upload and Post Snippet. xD
