Idea: graphical NPC/world editor

[Drawde]

Using the NWN toolset/editor gave me an idea for a similar (though much simplified)
utility for EQEmu. I've often wanted to create a custom world for EQEmu but have been
put off by having to work out the location of every single NPC by using #loc and writing
down the results! Converting ShowEQ lists is fine for recreating the standard Verant EQ world, but creating a custom or modified world is a very slow, tedious process.
So what about a graphical zone NPC editor? EQEmuAdmin has a 2D NPC location
viewer/editor (very slow however), I remember there being a 3D zone
geometry viewer in the past, and there's also an object/NPC model viewer; would it be possible to
combine these ideas into an editor that lets you view the zone geometry in 3D (if texturing isn't possible,
wireframe or flat-shaded would do, and be faster as well) then click on a location to place a NPC, or an existing
NPC to move/edit it? Maybe it might be possible to eventually combine the editor with some of EQEmuAdmin's features,
like the item viewer/editor, to create a full "toolset" for customising the world.
Just an idea, but I was wondering how possible it would be.
