imo, once a buff is completed, it should be made available (at the star button) instantaneously, without waiting for the whole "command" to finish.
that would eliminate the need to click 25 times in order to place 25 orders of ONE buff, and be able to only make one order. it doesn't make the game easier nor harder, it just adds to the game playability (less clicks).
once the next buff in order completes, it would simply add to the previous one in the star menu, in case that wasn't already used, ofc.
