as the subject says ...
until today, i was not aware of those two additional mods to change limitations of this mod.
only after looking up something and therefore reading lots of discussion threads did i notice that there are two really useful mods to let people configure more/other details (with the option to make their game unusable when using extreme values :-) or maybe i only didn't find those hints in the normal info page? the FAQ only links to one of the two additional mods ...

https://mods.factorio.com/mod/WideChests
https://mods.factorio.com/mod/WideChestsUnlimited
https://mods.factorio.com/mod/WideChestsAllTypes

btw: someone else wanted to lift the limits on settings in this mod and probably also didn't find those two supporting mods, and therefore has published a copy of this mod with the same name, same version number, same icon, and no description (no link to this mod) and the internal name "fixedMergingChests". although this and the other mod both are published under MIT license and thus it shouldn't be "illegal", it looks quite strange to have almost identical mods. both mods have Atria mentioned as author in the info.json, and both mods only list the license in the mod portal description without including any license file or copyright notice in the zip file (and thus: has the MIT license to be respected at all?) ...

These 2 mods are quite new (since 3.0.0 version). They are listed in optional dependencies, in main mod settings which they are modifying and one of them is in main mod FAQ. But you are right, I forgot to update main info page and will do that today.

About the clone mod: it seems to be connected to a bug found in my mod. The author of clone mod probably fixed it for themself and published in case someone wants to use it. I'll check what exactly was changed, test the bugfix and publish "official" fixed version today.
