TL;DR

Change the priority of the modules that are inserted into machines when shift clicking

What ?

Right now when I have 3 of the uncommon quality 2 modules in the EM plant which give a 2.6% quality bonus and I want to fill out the remaining open slots with normal quality 3 modules which give a 2.5% quality bonus, after shift clicking the quality 3 modules they also replace the 3 modules already placed in the EM plant. Same goes other way around, if the modules in there are quality 3 you can't shuft click the quality 2 uncommon modules to replace them. So what would be preferred instead of just checkin the level or just the rarity of the modules to check the bonus that the module gives you and replace them only if the bonus is actually higher.

Why ?

to make inserting modules guarantee you'll always shift click in the better modules and not accidentally lower the bonus and also prevents the need to manually take out modules one by one if you're dropping in the module level but raising the quality to get a small % boost

what:
when i press z (drop item) and slide over machines with modules in my hand it replaces lower tier modules if the machine is already full of modules, this is great QOL except for a tiny detail, it should replace if the bonus is bigger instead of if the tier is higher.

why:
some higher modules of a higher quality have a bigger bonus than a lower quality of a higher tier module, in this case i was putting quality modules in my recyclers on fulgora and noticed that my normal quality tier 3 modules (+2.5%) were replacing my uncommon tier 2 modules (+2.6%) even though it has a lower bonus, i think the +2.6% should replace the +2.5% instead.

1. ctrl-click on a building with module that gives a better outcome should be automatically accepted
for example: building has Quality 3 Normal (2.5%), ctrl-click on it with Quality 2 Legendary (5%) should replace the modules

2. force replace modules to whatever you are holding
for example ctrl-shift-click holding a module will replace whatever modules are already set there, even if worse
