Delta tweaks
by JJJassssper
Delta tweaks is a Fabric client-side mod that adds PC management, egg hatch tracking and visual tweaks for Cobblemon Delta players, released under the MIT License and not open source.
What it does
In the PC, the mod adds a multi-select toggle that lets a player pick several Pokemon at once, then release them or move them between boxes with a single button. The release button shows how many Pokemon are selected. A PC Tweaks tab collects the enhancement buttons, which can be switched on or off individually. Information widgets show IVs, aspects and breeding details on screen, and the Pokemon overview displays marks and ribbons. Borders are coloured by quality: perfect IVs, shiny, radiant and perfect shiny Pokemon each get a distinct gradient. The daycare and egg backpack gain outlines in the same colour scheme, and a Red Pokemon indicator marks matching entries.
Egg hatch counting tracks which species have hatched, with on-screen trackers for total hatches and shiny count. Up to six trackers can be shown at once, each with close and reset buttons. Hatched Pokemon can be counted, claimed or released automatically. Alpha Pokemon can be made easier to see by hiding their red particle trail and eye effects, and small Alpha eyes keep their red texture. Bag tooltips preview the contents of Delta bags. Settings open with F9 in game. The mod needs Cobblemon Delta and Fabric API. Only the client needs it, and the server can run without it. Builds exist only for 1.21.1, with 1.2 as the latest file from 2026-10-03, and the first release came out on 2026-08-14.
