I don't want to drag on the one piece of bad news for the week but do you plan to re-address it in the future? Also i'm just going by the name here but I assume this is about the bug that causes strange crashing when removing a part, hitting undo, and placing the held copy elsewhere? I have lost a few large craft files to this bug so it seems to me like at least a quick fix like deleting the held version when when hitting undo is warranted for the headaches it can save (maybe accompanied be a little message reminding people that a proper duplicate option exists).
