Hey team,

Im using wp 3.5.1 bp 1.7 Ok i have a responsive layout and i wanted to get more user friendly with the post updates. Now when you click on the post button, the box dropdown and you type whatever. The problem is the box is small and it moves if you tap the screen making it hard to write sometimes.

Now i want users to click on the button and it opens a new window that takes up the entire screen that allow users to post just like fb or g+. How would i open to the new window and its still connected to the post update button?
