That page is on my ToDo list.
But (all) links currently in your menu, such as Weather Forecast - Wayzata, MN, go to a new tab/page in your browser.
Already you can include them in your menu so that the info is displayed inside the w34 page.
Just check the demo pages in the download, such as
an image / div without an iframe=> http://release230/pwsTEST/w34_start_frame.php?frame=test_image
an iFrame =>http://release230/pwsTEST/w34_start_frame.php?frame=test_website
or the weather-warnings in your current setup https://www.loweprofile.com/pws/w34_start_frame.php?frame=weatheralarms
