Add a mod or setting to existent mod that restores the enchantment glint for 1.19.4 and newer players, allowing them see the 1.19.3 and before enchantment glints on other player's armour.
In 1.19.4 and 1.20. Mojang almost removed the enchantment glint for armour, presumably for visibility on amour trims. I have been playing around with 1.19.4 in a small survival server and the new changes to the glint have made it virtually impossible to tell whether or not another player is using enchanted armour.
This could be game breaking in PvP as you are unable to tell if you are fighting someone in raw armour or protection armour which is a massive difference.
Potions also had their enchantment glint completely eliminated, however the shinypots mod solves this issue.
