The new Open All Inventory setting

You can resize them. On controller it's R3 while focus is on the window. PC must have some equivalent. It works with lots of windows: inventory, character, crafting, etc. Press it repeatedly and it cycles through several possible sizes.

[EDIT: found a Reddit thread that says on keyboard it's Control + Home while the window is active.]

Yeah that's when you're in the HUD layout. The inventory window doesn't have a HUD element to resize.

You can use R3 outside of the HUD Layout. If you don't play with controller, you can use your mouse to right-click on the header part of the window you want to resize and press scale window.

Thank you! At first when I changed to the Open All setting I was like "OH NO! The icons are smaller!" and then I saw this thread and your post and all was better. So glad to have this option of not having to switch tabs when looking at my inventory anymore!
