We really should agree a rota for who replies to this topic, since someone raises it so often. My turn, but can we have a volunteer for the next one? Probably sometime in the next half hour.
No one complains about instant refuel, refit, etc., because if they were not instant there would be nothing do do other than sit and watch a cut scene. That would not be fun after the first couple. That is quite different to it taking time to transfer a ship, because you do not have to wait for it. You are sitting in a perfectly good ship, and can do lots of things. Such as play the game.
OK, if you were able to send your ship off to be repaired, and get in another one (either one of yours, or a loaner, or one you rent - for gameplay reasons it must work for the noob in his sidey with no other ship) then it would be fine for it to take some time to do repairs. Eventually you will be able to go walkies in the station. When that comes, taking time to repair the ship would also be OK, as long as there are things to do when you go walkies. But at the moment, with nothing to do, having repairs take time would not work.
