@Vitalis95 and @lilyclements this already works and that's a wow! I really like it.
a) The one tiny edit is to check the intial order factor levels checkbox by default. So it should always start checked, and reset should make it checked again.
b) Initially the checking of that item didn't work in my test version. That's a temprorary limitation that the original version of the 4 packages is originally attached. So it doesn't find Lily's new function. Just detach and then attach (library) again and all works.

@rdstern , it's now checked by default

@Vitalis95 and @lilyclements many thanks, that's great. And quite important. I can now finisdh more of the next presentation ready for @berylwaswa.
@N-thony over to you to approve and hopefully merge.

@Vitalis95 this looks, I'm approving. I can see you made the database changes, it will be good to include the screenshots of the changes done there too.
