Backpack Side GUI
by Locknar
With Backpack Side GUI installed, a Sophisticated Backpacks panel sits beside the inventory of chests, furnaces and other container screens.
What it does
The panel shows the contents of a backpack next to the open screen, so items can be inserted, extracted, swapped or merged without opening the original backpack window. Mouse wheel scrolling moves through the contents, drag-to-distribute spreads a stack across slots, and a double-click gathers matching items. Stack upgrades from Sophisticated Backpacks are supported, including stack sizes above 64. Backpack detection also covers Curios slots when the Curios mod is installed.
Item operations are handled on the server, so the mod suits multiplayer. A show/hide button toggles the panel, and the client configuration file, generated after the first launch, sets the side, the horizontal and vertical offsets, the number of visible rows and the hidden state. The required dependency is Sophisticated Backpacks, which must be present on the client and server for the panel to work. The mod is released under the MIT License and is not open source. Files exist for Forge and NeoForge, with the latest NeoForge build for 1.21.1 in the beta channel.
