Hi Bruce,
you are right. Many programmers (me included? 😊 spend most of their time in thinking about functionality and nice features often forgetting usability. Therefore the User Advisory Board is a very good and important idea.
Keeping this in mind, I agree that user interface should be changed in some places to solve conceptual and terminology (-> i18n 😊 problems.
Regarding move-option:
This add-on should not be a workaround for conceptual problems like fake "new" posts in order to allow a community/class admin collecting postings and building one thread, but it should allow some kind of moderating.
At the university of Heidelberg there are some professors which highly use forums in their classes/courses and even base graduating on them. Possibilty of moving postings was one item of their "wishlist" in order to split up threads covering two or more subjects after discussing a while.
