In creative mode, please fix the mod so that it can fit in the box by dragging the shulker box with the mouse while pressing down the key

There are two types of creative inventories: the "Creative Inventory" (the one with tabs from which you can take unlimited items) and the "Creative Survival Inventory" (the one where you can equip armor). The problem is that the first one is quite old, I would even call it legacy. Back in the day, some genius decided to implement it almost entirely on the client-side, and since Packed Inventory is a server-side mod (except for the keybindings, which are created to send commands to the server), it's impossible for it to manipulate or even recognize a client-side inventory. To "fix" this issue, I would need to fix Minecraft itself, specifically its legacy code. And I firmly believe that this is beyond the scope of this mod. Especially when users can easily switch to the Creative Survival Inventory (by pressing the chest icon in the regular creative inventory), which is server-side and therefore already compatible with Packed Inventory.
