For writing, I like the split that gives one window about two-thirds of the screen and another window the remaining third. For research, I like two equal windows for reading and taking notes, or one large window with two smaller ones stacked vertically beside it. Spreadsheets also work well in the two-thirds layout. You can also open Snap Layouts by hovering over a window’s maximize button or dragging the window to the top of the screen. Once you build a layout, Windows treats those apps as a Snap Group.
