This hack is fantastic. Thank you,

One thing I've noticed and I'm not sure if anyone else is experiencing it (testing on 3.8.4). When I have the attachments enabled the Quick Reply loads between 1 - 2 seconds slower than if it's disabled. It doesn't matter whether or not the attachment box is visible or if it's applied to Quick Reply or Quick Edit. It's not a big issue but I thought I'd mention it.
