I noticed the chest don't automatically enable the "request from buffer chests" when using buffer chests, could you support such a function to auto enabled from buffer chests?

Sure, I can add that functionality. How would you like it implemented? A map setting, with the default set to false? This would be the simplest way for me to do it, as I feel like not that many people are using buffer chests, or do you think this should be on by default?

I've gone ahead and released this feature with version 1.5.0, implemented as a map setting with the default set to false, as I proposed earlier. Let me know if that works for you!

I have to use buffer chests when it comes down to multiple quality items and I can set the item limit of each quality in a single chest. Active/passive chests don't accept different quality in a single chest, so buffer has to do.

Thanks for the feedback! I understand you’re using buffer chests to manage multiple quality items in a single chest. Does the current implementation with the map setting work for your needs? If not, let me know how I can adjust it to better suit your use case!
