several missing bags

If you wanted to add them yourself, I would describe them as "Extra Large Item Bags". The names for bag types are mostly arbitrary on this page; the only reason medium bags are named as such is because the game's first examples were both named as such.

The list is also missing bags like the Welcome Back Bag and at least two types of Drawstring Pouches.

It would be better, moving towards semantification, if we categorized them more logically.

Regular Bags -> Medium/Beginner/Eirawen/RM Welcome Back, Doll Bags[can easily be its own category], Exclusive Resource (Regular) Item Shop Bags -> (no subcategories, unless we account for Kiosks here) Unique Bags - > Carasek/Black/Star, Birman, Improved Birman, Exclusive Resource (Unique) Resource Bags -> Gold Pouches, Check Folios, Cobweb/Leather/Etc. Pouches, Quiver

There's no point in really editing the page right now though to reflect this, so long as it remains updated.

in that sense, I'd be inclined to include them as Unique Bags since you can only hold one at at time hm?

Yeah, but the closest facsimile as the page stands is Extra Large Item Bags (since they are all bags that you can only have one of).

I like all of this talk. If someone could come up with a nice semantic editor for the bags, that would be awesome.

that it would be, unfortunately my skills with the code language on this wiki are pretty weak. I'm mostly limited to stealing the format from a different page and swapping out the values and pictures
