I haven't searched to see if this was once a wishlist item, but what about adding a feature where you could type a friendly base name into once of the radio channels to get localized text and/or conversation, if it was in the voice channel?
Now we have the 'Room' channel, which may not be useful if you're a few sectors away and people are typing on another base's 'Room' channel, but if you could manually type in the base, you could get localized conversations.
