I ended up screencapp'ing my start screen numerous times with different apps installed and adjusted tiles for different sizes (rectangle, full square, small square). I then emailed the screencaps to myself, copy and pasted the icons into Paint and adjusted them to resemble a 1520 (approximately 5-and-a-half rows of full rectangles). Certainly not the most elegant solution but it works - gave a really good approximation of what to expect for the Start Screen tile layout without having to scroll down - can't believe MS doesn't have an online option (i.e. "Build Your Own WP Start Screen") anywhere on their website to show its "customizability"...is that a word? lol
Screencapp'ing and Paint - are we back in the 80s, now?!? lol
