I would welcome any improvements to the BGS gaming for ED.
I personally would like to see a new menu screen that displays a real time or a delayed log of the names of active CMDRs are who are fulfilling missions, trades, kills, etc in the system so that you can get a feeling that there may be other CMDR's that are watching what you are up to, especially if there is a player faction present in the system. And because your name and activities are known within the system, it would add some suspense when you see another CMDR's docked at a spaceport or in SC.
I think it would also add a real feeling of danger especially if you are a hostile in the system and this would make it something. (but it would only work in open mode only)
It would also benefit any CMDRs who are working that system's BGS to start to hunt down or make diplomatic contact with other CMDRs and make players play a role of enforcers or troublemakers.
But it would also probably need SOLO mode to be excluded from PP and any BGS manipulation inputs and any changes to PP or BGS to be available in OPEN mode only.
