Yes it would be nice to be able to stack a maximum of two filters from different categories, once the map starts remembering what we have selected under the current system again.Yeah, I did not explain at all.
What I meant was that I would like the option to be able to use any normal filter (ecconomy, star type, state, or none at all etc.) while, at the same time, be able to see which systems I've been too.
This would pretty much only useful when out exploring; which is exactly what I want it for.
