in the center section in the upper part of the gui should be a icon of a camera ,,pic browser ,,beside it is a little arrow to the left ,, push the arrow and it will toggle to text ,, to the right of the icons are tab labeled presets and edit ,,
yes it does split the screens if this is enabled ,, the icons at the top that look like a film clip ..
if you go into preferences and enable tool tips ,, by hovering the mouse over controls they will inform what they are for
hate to say play around with the software to become familiar with it ,,
as for the web cam try looking in the video tab and see what it explains ,, havent gotten that far ,,no web cam ,
