Cross-posting here from the script request thread so others in this thread will potentially see it.
Even though polv beat me to the punch and got something out that still meets your needs, I presume that there will still be people who want the same functionality as the original script. For those who want to give it a try, here is the updated version of this script.
I renamed it to be more descriptive of what it actually does.
There’s just one little thing, and that’s that I haven’t tested the actual button out yet, because I do not wish to skip any lessons on my account. If anyone is willing to install this and give it a shot, let me know the results here (you may want to have the browser console open before you click it, just to see what errors show up if any so you can post them here; open it by pressing F12 and going to the “Console” tab).
Edit: I have now tested it myself after help from @chrisl17 and confirmed that it works as it should. This should now be a direct replacement of lesson cherry picker.
If it is a popular request, I would be willing to modify this script further so you can quick-add to review queue any item, not just vocabulary.
