My Progress Bar: A progress bar for your workday
1) Click on 'Show Settings' and select the times you start and end work.
2) Also in settings, select 'Disguise' so nobody will question this.
3) Now set your browser to full screen mode (F11 usually does the trick).
4) Hide everything on this page except for the installation window by clicking "Hide Instructions".
5) Now get a cup of coffee, do whatever it is you do when stuff installs and enjoy your work day progress.
