without 2x you'd probably have to make the inventory window slightly larger, but it would still work. it's small but it would reduce clutter a little.
For me this would make the interface much less efficient. It would add an extra step every time I needed to access the pocket dimension.
I was thinking that most people would use their inventory when they go to the Pocket Dimension anyway (dumping items, crafting, etc), so by having it there it saves steps haha.
