[Controller] Loot pickup bound to main action button

I don't know if binding of actions will be available at 3.18, but currently loot pickup is bound to the "A" button, which is also one of the 4 main action buttons. This means you cannot use this action while you are standing on loot.
If your inventory is full you won't be able to pick up the item, or use the ability.

Even if binding is available, loot pickup should be bound to a less intrusive button.

The same goes for all the interact options. Having an Archnemesis Inventory open up instead of using a primary ability is rather jarring.

I agree. I am having this same issue. I am going to try a very strict item filter from https://www.filterblade.xyz/ and see if that helps. otherwise, I vaguely remember in the past that POE had the same issue with keyboard years ago until GGG patched it.

Regarding the pickup button being something different, they should just allow mapping and let the player decide how they want to map it.
