New Redstone Block: The Tracker Block (1 Block Entity Detector)

I propose a new Redstone block called The Tracker Block when a selected entity enters the block space. ​Emits a Redstone pulse when a selected entity leaves that block space. ​Selectable Targets (Via GUI - Graphical User Interface): ​The Tracker should have settings to choose which entity type it follows, such as:Players ​Items/Projectiles (for accurate sorting/detection) ​Hostile Mobs ​Passive Mobs ​This block is essential for compact, high-speed, and precise entity-based Redstone systems, allowing engineers to reliably sort mobs and items withunparalleled accuracy.
