How difficult would it be to highlight current valid keys in the Keychain section of the PDA? Say make it yellow or some other colour.

Once you start to accumulate them it would be nice to know which are valid rather than having to check each one every time before going to a station.

Or sort them into Active keys and Inactive keys. Searching for a key is so retarded, trying to see what tiny key detail has a bit of yellow in it.

A couple of guild mates have had questions on how to quickly tell if your key is active. Sounds useful.

Keys should also be differentiated by type, whether station or trident.

Station keys (alphabetical)
then other active keys (alphabetical)
then inactive keys (alphabetical)
