In addition to DrMezmerro's suggestion of being able to plant more than one seed at a time, can there be something to prevent buds being dug up when you are trying to plant a seed? EG I'm trying to plant a full field, going from one plot back to the seed and back again, and I accidentally click on the plot below the one I'm trying to plant and the bud gets harvested. Given the expense of the seeds, this is heaps annoying.
I thought the easiest solution to both this and Dr Mez's issue would be if you click on a seed, it is selected and if you click on an empty plot, that seed gets planted so a) you don't have to go back and reselect the same seed to plant in additional plots and b) it doesn't harvest anything if you click on a plant. Then click the seed again to deselect and then be able to harvest, change soil etc.
