We should be able to dig up plants before they either mature or die of disease- while they are still growing. I know this idea sounds like a horrible mistake, but think about it this way: you probably have hundreds of potato and cabbage seeds cluttering your bank that you can either throw out or plant. the problem is that they give horrible exp and are a waste of time. my solution is that you can plant them for exp, then immediatly dig them up and plant a new one. This would be an easier way to gain small amounts of exp, and would finally give a use for those annoying onion seeds clogging my bank.

That's why they don't have it, easy exp and it takes no effort.
