I understand what you are trying to say. The only reason I recommended this script is because I tried the reorder one before myself but found out I did not like it because it messes up the ordering of the vocab.
To respond to your point above, I don’t either. I learn the radicals as soon as they are available. Because you can define how many of each type of lesson you want, it will filter them for you in the order they were intended but with the specific types you indicated. I find this helpful because I am a 10-lessons-a-day acolyte. As such, I can define how many kanji and how many vocab I want in a day. I do a mix usually 4 kanji-6 vocab. I find that this distribution allows me to not level too quickly that I have a huge backlog of vocab waiting.
Anyway, I thought you were going for something like what I am doing, hence my suggestion of @seanblue’s wonderful script. So apologies if I assumed wrong, it seems the reorder script is really what you were looking for. Regardless, the mere fact that you are thinking of ways to better your lessons and reviews is already a step forward.
All the best! Hope to see your golden 60 badge soon!
