I have every possible jman spellcraft formula there is. Was fun collecting them over quite a long time. Recently I finally leveled up jman to expert spellcrafter and now can use Experts. So now I'm replacing all my jmans with experts as I find them. Some were very difficult to find and it almost hurts to delete them, when I find the Expert versions. Some were gotten from formulatron and was extremely expensive.
My idea/suggestion would be able to click a formula, in the knowledge book, and have them converted back into a formula in the inventory. Maybe either with a certain skill/level (papermaking maybe), or charge a scaling fee to do this. Then they could then be resold on connie or given to another player.
Or maybe when its pulled from book to inventory, it would be a 'torn formula' and needed some sort of 'repair' done to it before it is usable (scribable) again (again a level/skill or fee). The second option sounds way more complicated tho, quite a bit of programming, database revamping. But the first option is my wish list
