Well, I know that and that tool would be great, go Berserker!
Myself I have a clean WoG in second folder and I simply replace the messed one when need (takes about 3 minutes to replace +run patch 1.9.) I guess that happens to every one which is working on intensive modding. But standard players should be protected form editor overload so that tool would be great. Waiting for it.

I see Phantom used this to delete things (in action.txt)

DELL "AVXskds4.def" W+"data\"
DELL "AVXskds4.msk" W+"data\"
DELL "AVXskds4.msg" W+"data\"
DELL "dragbone.def" W+"data\"
DELL "dragbone.msk" W+"data\"
DELL "dragbone.msg" W+"data\"
DELL "zmagic00.def" W+"data\"
DELL "zmagic00.msk" W+"data\"
DELL "zmagic00.msg" W+"data\"

is this the right command? Need to remove codes as well from ZEOBJTS.txt, right?
