Personally I find myself with a lot of adol cubs aged too high to be sold as fodder and sitting in trades.... a lot of trades. Then I have to cancel each one individually so I can drop them off at the tree.

I'd like to see a 'Cancel all' trade feature. I don't know if such a thing would overwhelm the lioden servers or script or whatever it is, so maybe as an add on you can only 'cancel all' once a day.
