Copy/pasting with the mod is a little annoying since there's a bunch of different quality buildings in the copy. With the upgrade planner you can select and item, choose any quality, then upgrade it to its normal quality. But you have to do it for each individual item, there's no way to have it upgrade any item at any quality to the respective normal quality item.

It would be great to have a tool built in that does exactly that. Quality Upgrade Planner does allow this behavior, but it would be preferable to have something like that built into Quality Control (just upgrading everything to their respective normal qualities, without the extra features) to avoid dependency on another mod.

Totally agree! Thank you for raising this.

I'll look into adding support for something that makes copy/pasting easier. I'll update the thread when I make some progress.

Regarding going from 'copy any quality' to 'paste any quality (highest preferred)' and similar, factorio's API doesn't support the concept of building 'any' quality. If no quality is specified it always defaults to normal. There could be some more advanced handling, like determining the highest quality item available in the network or players inventory, and using that. I think that would take some time to develop and debug properly.

The placeables mod does something a bit like that, where it chooses the highest quality item in your inventory when selecting from the menu:

Anyhow, thank you, just writing about how I might approach the problem for later reference. I'd like this feature too.

I feel the same problem however, that match a mod I have in mind. The mod would order fast replace building that have better quality in the network when possible, for example you have a logistic network that have better quality furnace, the mod would automatically order an upgrade. Either at random or pick the "most used" entity first. The dream would be to be configurable. Like "don't upgrade laser turret more than uncommon.

And so in the same spirit but that would solve the current problem with copy paste a mod that see you order to build an entity but you doesn't have it with this quality and replace it with available best quality available.

Right on, that would be so cool. A non-cheat version of this mod is totally doable.

I like the idea of putting a max quality on replacements too.
