...planted crops should behave like other constructions, I feel. Either be Red in a 'bad' location[too close] or allow the construction to be removed/deleted; as is, mechanics allow for bad placement to be informed only AFTER the placement??....I find no way to 'unplant' something, although there seems to be a control hint that says so? Middle mouse button or whatever, no such button on my mouse with scroll wheel[which depresses] or the 2 side buttons I have...does that.

I did manage to get some flax to 'regreen' after some nearby ones were harvested, only crop I've seen do this, the others seem to 'disappear' when all other crops in vicinity are 'ripe'...carrots, barley, etc...never go back to green and become harvestable.
