[Feature] Enhanced Window Management for Ultra (Ultra) Wide Monitors

[johnnyq]

Ultra (Ultra) wide monitors, such as the Dell 49" U4924DW with a pixel resolution of 5120 x 1440, often don't receive adequate support on Linux. This resolution provides ample space to comfortably display three windows side by side. I suggest enhancing the window snapping feature to accommodate this: when snapping a window to either the right or left side of the screen, it should automatically reserve space in the center for a third window. Thus, when you drag another window to the top of the screen, instead of it expanding to fill the entire screen, it should only occupy the central portion. While I'm not particularly inclined to use tiling functions, I find the snapping feature very useful. Ideally, this behavior would be enabled by default on monitors recognized as sufficiently wide, though it should also be customizable.
