= 1 Display Case. Always shown with a base made of "oak".
Right-click to change content: Swap whatever stack is being held with Display Case content.
The stack is displayed inside item case the same as when it is a floating item, ergo a stack of several would look like a" group" of the items. However, the displayed item(s) inside the display Case would be non wobbling and non-rotating.
Left-click to break the display case: The Display Case item, plus the stack it contains, both drop on the floor. Like breaking Item Frames, this is a very quick action.
This is stupid you took the idea from DanTDMs Modpack 100% NO SUPPORT
And BiblioCraft. And Equivalent Exchange 3. Also, they didn't steal the idea from your friend's modpack (Not that they "Stole" it at all), they got it from the mod itself. The modpack compiler did nothing more than compile, leave the credit the modder himself. :3
Now that that's over with, I don't really see a point in this, since we have item frames... No support.
1: Putting "Now with X supporters" in the title doesn't make people think the suggestions bad, but it doesn't attract people as well. And I can clearly see from where I'm typing it says in the title "Now with 19 supporters" I suggest you remove the supporters thing and just let the supporters trickle in. THEN you can put it back in the title.
2: A mod called Bibliocraft has pretty much the same thing. Maybe you could configure it a little so its not like a mod?
