Right now, as far as I can tell, the only thing you can do with the “move to the front of lessons queue” option is just that; you send something to the front of the lessons queue and then that’s that. As far as I can tell, you don’t even know what order they can come in, which is a shame. If I open the manage deck function on the 10k deck page I can’t even see what the lesson queue actually looks like; I can display every card that WAS brought up to the front, but not actually in the order of when they’ll show up. And it doesn’t look like I can do something like bringing up a specific word ahead of time or sorting the queue by a specific criteria, which would be handy. It’s not a ASAP MUST HAVE FEATURE but it would be nice to have going forward.
