Blizzard protected the function DeleteCursorItem(), so auto destroy is no longer possible. However, the function can still be called in response to a hardware event.

how to call hardware event ?

I have to update the addon to provide the ability. A lot of code needs to be reworked to support the change, but it shouldn't take too long.

so, autodestroy can still work with hardware events?

Not properly. I'll be implementing a UI with a button to destroy items one at a time instead.

well, we'll wait! your addon is really very good. I'm wondering "manual destroy" will work in combat? and will you make it possible to bind this button for destroy.

Yes, destroying should work in combat still. And there will be a keybind allowing you to destroy items without going through the interface (again, one item at a time to avoid certain issues).

sounds cool! I will wait
