NSFW tag box improvements

As discussed here until we have proper tag categories, I can whip up a quick NSFW tab in the tagbox (the one that is there on the upload page, when you Edit Tags and Source, etc). Besides, even if/when we do have proper tag categorization, you probably don’t want “popular” or otherwise somehow automatically sorted tags in there.
 
Anyway, there’s two important things I need to know for this:  
-> 1: Under what conditions should the NSFW tab even be accessible? I can see it having use for questionable pics, not just explicit. Plus, it’s not like the tagbox will mention “explicit” etc in the System Tags column anyway.  
-> 2: What tags should be in there? I can understand a column(s) with the important stuff like gay, straight, lesbian, solo female, futa on male, etc (the most jimmie-rustling stuff) but I have A) no idea what would be logical to do, and B) there’s probably more important/jimmie-rustling tags I’m missing/not aware of.
 
Keep in mind that we’re not going to list everyone’s niche fetish in there. The people that upload that are all very aware of what their particular fetish tag is anyway, so they should just tag the damn thing.
 
Current limitations mean there’s space for about 5, possibly 6 columns of tags, each 10 lines of content (of which you probably lose one to the bold column title).  
_{And yes, no matter how easy you make it, there will be users not tagging their uploads. Also users complaining in comments about things they can. just. hide}
 
So. Discuss! Don’t forget to subscribe if you want to at least follow the thread. I’ll let this up for some time before I start making any sort of concrete columns and stuff.

Oh, I guess anatomy stuff could be a column. penis, vulva and so on.

it should have the nudity tags as well as breasts and crotchboobs, penis and horsecock, vulva, vagina, futa, human on pony action.
 
maybe even some of the more kinky stuff from lingerie to bdsm, ahego and bukkake. those seem pretty common.
 
i’m not sure about incest, selfcest, bbw and other special tags like multiboobs or vore.
 
some of them are pretty frequent, but aren’t used that much as they should. meaning, those are often forgotten to tag in correctly. like bbw, ahego or bukkake.

The ‘cests probably aren’t necessary, anything that’s on them that’s bad should be tagged as something else anyway.

I don’t get it.  
No comprende señor.

Grrr. I just remembered I also have a bunch of tag alias backlog to go through still. I know somewhere in there is something regarding bbw/obese/fat/whatever for which there are like 10 different tags and I have no idea if there’s some sort of logical ordering in there.

You know how there’s that box on the upload/“Edit tags or source” page with spoilers and pony name abbreviations? It has tabs, and (at least) one tab should be dedicated to NSFW stuff. I’m seeing that box as a sort of “when you upload an image, you have to at least click through all the tabs and click any tags that apply to your image”. Seasoned uploaders will know most of the tags anyway, but a lot of content comes from occasional uploaders, and is often undertagged, like a forgotten crotchboobs or futa or solo male tag etc.

Many users tend to forget tags like penis/vagina/anus/etc very often, so I think these should be in the tagbox too.
 
Edit: Oh, I just realized that these tags were already requested, didn’t see that.  
Well.. just ignore this post ^^
