Second layer of filters for Formulas tab of the Knowledge book please

[hallucin8]

Is it at all possible in add a second set of filters available, depending on which type of form you select from the knowledge book? I addition to Type and Tier, I propose:

armor - equip slot
container - skill required
crystal - n.a. ?
dragon scale - base stat or equip slot
food - main, side, dessert, etc?
gadget - who knows... if it's possible, add some categories, e.g. keys, sunscopse, otherwise, I guess n.a.
jewelry - base stat or equip slot
potion - reaping, bolster (stats), and protection?
resource - skill required
scrolls - n.a. ?
spell - skill required to cast the spell
tech kit - n.a.
tool - skill required to make, and/or skill to equip?
weapon - skill required to make, and/or skill to equip?

I have no idea if this is possible, and if it were, would it add significant load to the server and increase load times, then no thanks. Surely it's possible to add a row to the database to hold this information if it doesn't already?

(It would be totally awesome if the Techniques Available list in the Item Creation window had a drop down menu to filter by Type)

Thanks for your consideration.
