i can only get 3 col layout on home page even though i have selected 5

  2. If you zoom out (e.g., to something less than 100%), you'll probably see an additional column appear.

  3. I guess the margins aren't really that significant. If you adjust the width of your window, you'll see that we do fill the full space if there's room for another column. So I think it's mostly just about the math in terms of how much space and how many columns will fit based on your scaling/zoom and resolution.

  4. I changed the program scaling to 80% and got 4 columns
