For @soundlogic2236.
Thaumcraft 4 Research Modtweaker Support is capable of moving research within tabs. So why not move Entries within Categories?

Unfortunately, it looks like the way entries are coded the category they are listed in is final. However, I might be able to write a function which copies over all the pages to a new entry. Functions which do multiple things at once will come, but I want to get all the 'primitive' functions out of the way and stable first.
