PopOut!

This module adds a PopOut! button to most actor sheets, journal entries, and applications.

The PopOut! button allows you to open a sheet/application/document into its own window, for easier viewing or for use with multiple monitors.

For those with more than one monitor this is a must, but even for those on a single monitor being able to tab between the windows is great for screen real estate management. Another must-have module I have been using forever. I left the baseline configuration alone.
