When scanning planets for resources (uh, it is obnoxious work — not fun!) there are indicators that fill up as you acquire more resources. (Eezo, Iridium, Platinum, Palladium)
Do these indicators show the maximum spare resources your ship can store? If so, how many resources is 100% on the indicator for each material? Or can you go over these limits? Or if you try to go over is the material wasted? If you go over this limit by picking up materials when not planet scanning (when down on a planet or space station), do you get credit rewards instead, like if you go over your Medi-gel limit?
