I think this was a song by Pieter, Paulsky and Maria, some time ago:
"Where have all my starships gone, one update ago?
Where have all my starships gone, one update ago?
Where have all my starships gone?
Gone to limbo, every one.
When will I ever learn?
When will I ever learn?"
This is very annoying, to have only half your ships showing in the list. You wind up missing some moves,
especially in an immense galaxy, with an enemy starting off at genius level, who seemed to have every tech in the book before
you even have a translator and who has built thousands of ships and is throwing them all into your zone of control.
With all that busyness going on, it's easy to miss single ships and have them get hammered by enemy fleets.
If there is a limit to the number of ships available in the list, it needs to be upgraded by another 5000 or so.
Why not add an option to toggle the display of fleets docked at planets, just to decrease information overload?
You barely ever move those little guardian fleets and they slow the game down if you have to scroll through every one of them.
