Not sure I agree on the first part, having to learn to keep track of a much larger fleet is part of the challenge. depending on how big your fleet is of course.. It would be nice to have, but it needs to be implemented in a seamless fashion and has to be intuitive to open and easy to read, which could be a problem for really big fleets..
There would simply be too many ships to keep it easy and intuitive.
The second part I agree on, I would love to be able to tell my fighters and frigates to retreat at a certain point and not have to babysit them.
For fighters I'd like 2 options, one to return to rearm and refit, 50% wing size, and one to retreat off the map, 25% wing size? obviously this would need to be tweaked for squadrons with only 2 or 3 fighters.
