While I personally enjoy finding all this naturally on my own, there are some items on this list I wish I knew about a little earlier compared to when I found out. Like Hot-keying weapons and aid took me a little bit to realize on Xbox, I also haven’t gotten as far in the main mission as they suggest, so who knows, everyone has different styles on how they play.
Another tip to access ship inventory: When you are close to your ship (<150m?) go to the ship menu (bottom left section in the menu) and you will have a button to access the inventory (X on Xbox). No need to climb inside the cockpit.
One small tip is that when you favourite your space suit in inventory you will automatically put on your helmet. One less button to press if you’re like me and take your suit off in atmosphere.
