Having to manually drop every single ore you don't want gets pretty old pretty quick, so something that allows us to get rid of multiple at the same time would be a great change. I have a few ideas in mind, but I'm not sure which would work out the best.
1) Option to drop all of x kind of ore. For example, being able to drop all copper ore in your cart at once.
2) Option to drop multiple of any mix of ores at once. Could maybe allow users to select multiple individual ores at once before dropping.
3) Option to "filter out" certain types of ores. Your wolf would still mine them and it would use pickaxe durability, but it would auto-toss anything you didn't want. For example, selecting copper and iron ore under the auto-drop option, so that any time copper or iron ore was mined it would immediately be dropped from your cart.
I like mining, but it's just a bit tedious as it is, especially when you get deeper in the mines. Any input or feedback would be great!
