Hello,
My suggestion is pretty simple, and I believe wouldn't be complicated to include into the game. It means implementing a preview system for items that contain other items, which would open an interface displaying those items. If you've looked the new server by X-Legend, you might have noticed that when you CTRL + left click an item that holds items, a window opens up displaying the different obtainable items.
For exemple, the partial enchant formula chest
would look like this when you CTRL + left click it.
This change is not going to make a huge difference nor that useful but I believe it's a nice feature to have into the game.
Thank you for your time.
Have a nice day!
