The mouse over update for items is great but I feel there is still a need for improvement.
With the current interface, you need to drag your mouse over the text to see what type of item it is. What I'm suggesting is put a logo before/after the item to be able to determine what type of item it is (i.e. turns, mining time, segments etc.)
Here's an example:
The item gives marines so it has a logo "M" before it.
Also, I want to put a color code in the logo like:
purple = common
green = rare
red = very rare
This will save more time since players won't bother to drag their mouse if they see that the item just gives a crappy bonus.
