   Oh how many times I've been thinking "I wish we had extra categories",
when I was writing long and cumbersome "just for me" inis with EditorIDs,
ton of values, and was envious of Skyrim and Fallout 4 keywords, while we
had nothing like that, even though it's a solid and very useful feature. 

   And oh how many times I've seen scripters filling their code with tons
of if statements checking values on item, praying it won't fail to return
exactly what they are looking for. "Is this a metal armor or some bikini?
If it's a light armor, why its rating is so high? What is it then? How do
I tell? What should my mod do with it? Do I apply my changes or not? Man,
I wish we had some extra categories for standardization!"                

   Dozens and dozens of such example. And probably everyone had something
similar happen to them at some point while modding. For me, the last drop
was inability to check activators without some sketchy code. Specifically
radios, harvestable plants, and switches. And not for the first time too.
It was annoying, and required either unreliable code, or reusing old mods
data over and over and over again. Or, what's worse, creating master file
as a resource and just use formlists...                                  

   Now you wonder, why not do exactly that? Well, because nobody wants to
use lists from masters files. People usually don't even use vanilla ones.
Game's out for more than a decade and even base things aren't categorized

   With KEYWORDS mod - it's independent from ESP(M) mods, simple to apply
not only by authors, but mod users without past modding knowledge at all.
Mod also expands possibilities for ESPless mods and kNVSE animation sets,
allowing them to get and use more data with less code.                   

   There's been a discussion if this mod is even feasible, but I strongly
believe standardization with simplicity might be successful. Removing the
annoying part from the equation, opening it up to wider audience, and who
knows. It might work. So, I asked Jazz to make Keywords functions for me,
even though auxvars exist, that could've been used in the similar manner.
Because I also believe that making something into an ini isn't enough. It
has to be also stripped down to it's bare minimum, syntactically as well.

  So, will this work? I don't know. It entirely depends on the community.
I know I'll use it. Already do in an upcoming B42 Interact mod. And if it
fails? Oh well, I'll know I tried. But I doubt it'll fail. I've witnessed
people making dozens of patches for much more difficult mods. And patches
for my own mods: Dropmag, Optics, ISControl, Descriptions (which is HARD)
So yeah. All we need is some dedicated fella with an idea - how it should
all be categorized and standardized. So, how will it go - time will tell.
