It would be really nice if somewhere in the codex there was a feature that allowed explorers to view their current undelivered cartographic data and its value both per system and total for all. The ability to see where we have been would help us to further explore specific areas such as clusters and nebulae. In addition, the ability to view on the galaxy map the systems that we have personally scanned, separately selectable the ability to see all systems that have already been explored or discovered by any and all players to prevent overlap and use as a tool for planning expeditions. This all will make exploring the galaxy more efficient and allow for greater coverage of all areas.
