Staff, if folks can write userscripts to claim all items then surely one of your coders could make this an option for your customers!
Whether or not it’s easy to write a script to click the button is besides the point. We have to consider the technical and user experience implications if we were to provide this as functionality. We weighed the options and it is not something we are going to provide. You’re welcome to run a script on your account at your own risk. I left a longer post up at the top of this thread explaining in more detail.
