Galaxy Map Icons

[Mohenjo]

So, I've been away a little while, and now I'm back I'm baffled by the many new icons on my Galaxy Map (such as a yellow square with a 2 circle Venn diagram in it), and the many new icons on the navigation panel (looking to the left).

Is there a legend or something that will explain what these icons mean?

Last tab (in the galaxy map).

Except the two circles (for some reason) - that's the market you have set up to compare market prices with, you can turn it off by removing the comparison market in the galmap filters.
