Now I want to ask how do I get it not to show so much information?

I guess there is no way of just having it show what you yourself have discovered and is shown in your ingame map? That is, if I haven't found it ingame it wont be on the map.

As is I would like to NOT know what yields asteroids got.
Not to know where uncharted gates are placed (I can live with it even if I have to remove all gate data from the map)
Not to show objects and ships etc.

Can I just remove the scripts that are responsible for that kind of charting or is there a better way?

I did try to do a quick delete of scripts but I didn't get the results I wanted (eh, no results at all actually - and I deleted them from ingame. Have added back everything now just so I don't mess up :P)
