rain hatch
Could not find any mod that does this, it allows you to press the backpack key (In this case B) while you are in a container screen to open the backpack, pressing B again will seamlessly return to the previous container.
Made for MrCrayfish's Backpacked, but could be adapted to any Backpack mod.
Not fully tested. It is synced with the server, it shouldn't duplicate items.

Wow, not even Sophisticated Backpacks let you enter their GUI from within another GUI
rain hatch
I'm planning to try other stuff as well like dragging items while switching containers or a keybind for transferring items directly to the backpack
