I wasn't asking for it to get implemented. I was just saying I was frustrated I couldn't find a way to do it and was wondering if I was missing something. Sorry for the confusion and apologies for inadvertent offense.
It would be nice if a script could access the Mementos, Junk, and Singleton lists you can make in the GUI (nicer still if you could define your own custom-named lists that had gui support). Because some of that stuff is PVP-able, for instance, so I was making a script to move the stuff I care about to my closet. Then I realize there didn't seem a way to use the GUI-based lists in a script. I know there's some scripts out there for this sort of thing already, but I enjoy making my own (part of the reason I play).
I've since made a script and copied and modified the item_flags.txt into a map.
I realize this could probably all be done via a script that has web-based GUI instead, but I haven't made one of those yet. When starting out a list like these, a GUI is usually quicker than CLI, since it is often hard to specify exactly why you want to keep or junk X.
Unrelated: I did come across a bug while working on this and submitted a bug report for it.
Edit: I edited my original post to make my question clearer and to get rid of the "annoying" at the end.
