A pretty simple suggestion, but for RP purposes I like to rename ships I buy to have a certain prefix depending on my current status, so ISS if I'm independent, PLS if under commission with the League etc. rather than leave them with the faction prefix of wherever I bought them, ending up with multiple different prefixes in my fleet. Although at the moment to do this you have to delete the entire name of the ship, which can be annoying, especially if you're not great at coming up with ship names and forget the original one.
So what I'm proposing is have two fields for the ship name, a small one for the prefix, say 4 characters max, followed by the ship's name itself. It wouldn't make much of a difference but I think it'd be a small quality of life boost for anyone who likes to role play with their ship names in their fleet.
