PenHelper
by ImLisa
PenHelper is a Fabric utility for players on a Pen prison server, bundling quality-of-life tools for stats, vaults, chat and inventory.
What it does
A stat tracker reports money, shards and keys earned per hour, and a shard goal display shows how far the player is from the next prestige. Vault utilities help the player open the last vault pages, and chat filtering hides repetitive messages such as tips, level-ups and haste notices. An inventory monitor warns when the inventory is full.
The mod is client-side only, so players install it and servers do not need to run anything. It requires Cloth Config API and Fabric API. Files are published for Fabric and cover 1.21.10 and 1.21.11, with 1.0.0 for 1.21.11 as the latest release, under the MIT License, and the source code is open.
Key features
Per-hour stat tracking
