hollowbytez/featherpojav — reverse-engineered prompt

Build me a Feather style client mod for Minecraft 1.21.1 that runs through Fabric and feels great in PojavLauncher on mobile, but also works on desktop. I want it to recreate the polished custom client feel with a nice main menu, custom settings screen, searchable mod list, and a drag and drop HUD editor. Please include movable HUD pieces like keystrokes, coordinates, armor info, fps, potion effects, direction compass, and reach display. I also want smooth zoom, freelook, a stopwatch, sprint toggle, auto text macro support, crosshair controls, and a simple time changer.

Please add the gameplay and visual extras too, like real 3D item physics when items are dropped, fullbright that restores the player’s original brightness when turned off, item drop confirmation, chat filtering, and some mobile friendly performance tweaks. Default controls should match the feel from Feather, like Right Shift for settings and Right Alt for the HUD editor. It is fine if this is an early version, but make it actually usable and smooth first. Look up current docs online if you need to.
