When the original version of PhpGedView (PGV) was released in 2001 internet browsers were relatively basic compared to today’s standards. So it was common to use pop-up overlay screens for functions such as edit windows. PGV’s were commonly about 500 px wide by 600 px tall and positioned somewhere near the centre of the browser screen. They were, in most browsers, the only way to have both your original data and the edit window open at the same time easily. However their small size meant many compromises to the content display, and as laptop computers and more recently tablets and smart phones became popular they occupied more of the available screen.
