I would like to request a new feature for Monitor Splits.

Currently, when splitting a monitor (e.g., into 4 quadrants) and placing windows within those splits, it can be difficult to visually distinguish the boundary lines between neighboring windows—especially when dark mode apps or windows without distinct borders are adjacent to each other.

It would be extremely helpful if there were an option to display persistent grid lines (vertical and horizontal borders) on top of all windows along the split boundaries, similar to the physical bezels of a multi-monitor setup.

Proposed Feature Details:

An option in Monitor Splits to enable "Always-on-top split boundary lines / overlay grid".

Customizable settings for the boundary lines (e.g., line color, thickness, and opacity).

Having visible borders on top of windows would make split-screen usability feel much closer to an actual multi-monitor environment.

Thank you for considering this suggestion! ]]>
