Staaaaaaaaaaaack (Stxck)
by frankV
Staaaaaaaaaaaack lets dropped items merge past their vanilla stack limit, which can reduce lag where many drops collect in one spot.
What it does
Drops of the same kind merge even when their stacks are already full, while the maximum stack size of each item stays unchanged. Merge distance, the largest size a drop pile can reach, and the size and render distance of the overlay can all be set in the config.
Items can be excluded from the extended merging by name, by item tag or by dimension, using a blacklist or a whitelist in the common config file. The mod is client and server, so the server and every player need it. Installation is for Fabric, Forge, NeoForge and Quilt, with files for 1.21.1 on the latest builds. Its code is open source under the MIT License.
Key features
Merging over the stack limit
Drops merge even when their stacks are full, and the stack limit of each item itself is left as it is.
Merge distance setting
The distance within which drops are combined can be adjusted in the config file.
Maximum drop size
A cap on how large a merged drop pile can grow is set in the config.
Overlay size and render distance
The size of the count overlay and the distance at which it is drawn are both configurable.
Blacklist and whitelist
Items can be excluded by name, tag or dimension, or limited to a list, from the common config or through a specific item tag.

Use cases
Busy farms and mining areas
Places where many drops collect in a small area are the main case the mod is meant for, since merging cuts the number of entities.
Who it’s for: Players and server owners who run farms, mining setups or other automated builds that produce large numbers of drops in a small area.
