One small improvement to logobots I'd like to see is disabling over-delivery to my inventory. If I request one stack of items, I don't want to end up with up to one stack + 3 items. For requester chests over-delivery should probably be kept, to reduce flight traffic.
You can set the logistics request maximum amount of the item to same value as minimum amount - though then if you want to pick up some more you have to adjust so the bots won't come take them away, but for me it's much preferable to inventory being filled from tiny extra stacks.
