+Subject: [PATCH] Configuration for horizontal-only item merging
+
+Most of the visual artifacts that result from having item merge radius above vanilla levels is from items merging vertically,
+which realistically, only happens when a player is dropping items, or items are dropping from breaking a block.
+
+Most of the scenarios where item merging makes sense involves the two item entities being on the same Y level. i.e on the ground next to each other.
+This is even more apparent since paper fixed items being able to merge through blocks.
+
+This patch allows us to configure items to only merge horizontally, which is what vanilla does.
+This allows us to have both the reduced number of item entities a high item-merge radius provides,
+without most of the visual artifacts caused by items merging vertically.
