Need a Mac application that will show upon running a split window, one on top of the other, and in each window will display a web page. this application should have a preference which will include the following:
for each one of the two windows - the url of the webpage it should display (the page include a php application)
intervals of refreshment display for each one of those sites.
the windows should be resizable.
Please ensure to provide time estimate and before the final product delivery i would like to see the screenshot.
