Saw nothing about where to post suggestions so I'll just post this here:

Now that you can place chests either apart or as a double chest in vanilla MC while the chests are next to each other it would be neat to see the same thing with Iron Chests.

Expanded Storage adds double chests.

@BLovegrove Are you suggesting to implement the possibility to have a Double Iron Chest, Double Diamond Chest, etc.?

yes exactly that - essentially the exact same functionality as Minecraft chests as they are now in 1.17 but with the larger variants (copper, iron, gold, etc.)

Originally Iron Chests was meant to allow people to have single bigger chests (Like the iron chest being as big as a double chest by itself). I'd like to keep this original idea, and do not make double chests possible. However, I will not close this Issue/Feature Request, as if many people will request this feature to be implemented, I will consider to actually develop it and make it part of a future Iron Chests release.

Neat - yeah I get where you're coming form there and I appreciate you keeping an open mind about potential features!
