Your idea is a step forward but from a practical point of view it seems a little unintuitive to me.
And only gets half the problem, players who want to extract a strong effect will continue to put aside weapons and armor just to extract it.
A better solution was suggested by someone recently but I don’t remember where.
The idea is Eleanor Extracts the effect instead of the ember but to insert the effect on an item you still need the ember, this way the chests are more organized.
Then, special boxes are added for non-accumulating items (such as runes, weapons, armor, and extracted effects), which have much more space inside them.
This is just one of the problems of the Enchantments I believe that we need to Revamp Enchantments on a much bigger scale.
If you’re interested I’ll talk about it here: The RNG Problem, Enchantment System & Gem System “TOGETHER” (Update)
