Gem bags & picking up gems

@Vic7im, that's the purpose of the horadric cube in this game so unfortunately it's not possible to simply take the item off the ground and place it inside of the gems bag with a single mouse click.
In the next coming patch however there will be one single gem bag allowing you to store and extract any type of gem of any quality but that's pretty much as far as the game allows it since the alternative of stacking gems that we thinked of before would be problematic during socketing and other similar actions. This 20 years old game has it's limits. Keep in mind you'd normally require 3 different gems for each transmute to upgrade to a next level gem so that's already saving a lot of time comparing to the original recipe.
