What: Move ore from your cargo hold to your corp hangar INSTEAD of to your items.
Why: The main benefit is that I don't have to interrupt my miners in order to move ore from my items to corp hangar. I only mine in .7 space or higher where office rent is pretty cheap. I have a separate hauler toon that I use to haul ore and refine. I usually haul it to a station where I have good standing and end up paying no taxes with zero waste. Which is why I decided to move ore to my corp hangar instead of items. Now I don't have to mess with trades or contracts and my miners can stay in the belts while my hauler does his pickup.
How: open your corp hangar window and position it the same way as your items window. You may have to increase the height of the corp window just a little but the width can remain the same.
Results: So far so good no issues that I can tell.
