For me, the most irritating thing in this whole feature by far: when you're on the colonisation ship transferring goods it is very tedious to navigate to the "transfer all" button by keyboard.
IMO this button should be selected by default, ready for pressing, and if for some reason you only want to transfer part of your cargo (by far the minority case, I would expect) you can navigate away from it to select the specific number of specific items to transfer. Also irritating, but not by as much: after pressing "transfer all" you have to go backwards (in terms of the usual semantics of the UI) to the confirmation button which could instead be navigated to on your behalf by the UI code.
Transferring from the fleet carrier cargo to ship is also onerous because there's no increments acceleration like there is in the carrier's commodity market. For this reason I found myself putting the delivery items in the FC market and buying them off myelf just to speed up the transfer.
