If your UI freezes you can reset it by pressing CTRL + U twice. [This is actually my fav...lol...need this one.]
You can trigger some bonus quest by attacking monsters on your way.
You will reduce the time for crafting by increasing affection with your companion. Also, the success rate on missions is increased with higher affection.
You get 450 exp for each crew skill trainer you visit (there are 14 trainers). [Not sure if I actually visited all of them.]
After gathering, you can leave your crafting materials in Cargo Hold (bank) and your companions can craft even though the materials aren’t in your bag.
Upon getting a star ship, you will have daily quests for space combat.
You will gain huge experience by doing Space mission quests at your level. The difficulty and the level of the missions does not change, thus, as you level up the space missions become harder and the lower ones grant far less experience.
If anybody has any other good links or tips, post them up.
