So, for all of us who want to level their mining level or just need a specific type of ore, there is one common problem. Out mining wolves just pick up the ore we throw out again and put them back in. Dropping all ore we don't want isn't just time consuming by clicking every single one, or tapping every single one and click Drop for every single one.
So my suggestion is: Add a drop all feature. So for example, you want to drop all Silver in the cart, click one Silver and then there is a Drop All bar and if you click it, all silver in the cart will be dropped.
This would help save some time and frustration as well!
