Played a bit more tonight and I'm only now starting to feel the relief of having storage containers make my life easier, but it's still a pain in the ass to transfer all of that stuff quickly, especially because your own backpack carries so little.
Thankfully they implemented some color schemes for the buildable elements, so here I placed various storage containers color coded to their corresponding resource types (green for trading commodities, blue for silicates, cyan for neutral, purple for rare etc.):
The major pain in the ass is that apparently you can't transfer items from the ship's inventory to the storage container(?), so you need to juggle items from your ship to your exosuit, and then from the suit to the container, which is insane, especially when you can't even stack items in your suit. Maybe I'm missing something, maybe the ship needs to be landed closer, but it doesn't seem to be the case.
Also, there seems to be a bug with the storage container as it's occasionally showing me item descriptions from the multi-tool while the cursor is in some between space or just over your inventory items, it's like the game is also rendering another invisible inventory grid below the one you see. I'm reading on reddit that some people have a similar problem with the freighter inventory, as it looks like it's kinda overlaying over an invisible exosuit inventory, so if you quick transfer an item from your freighter to your ship, you're actually "transferring" whatever is in your exosuit on that same slot, so you can end up removing and bugging out your life support etc. Haven't bought a freighter yet so I can't check it out, but just throwing it out there for people that have one.
