Phew, there is so much confusion about 7H.
First thing, I hate the catalog. Why? Because it turned 7H into another but more advanced Bootleg. That wasn't what I wanted it to be like, when I worked with Iros on it.
EQ2Alyza has my full respect for what she is doing, but taking care of dozens of mods is not what one person should handle alone. My idea was that every mod creator is making his own iro file, which he takes care of. I knew as mod creator as best what can went wrong when combining mods, because I knew what my mod does change. Sure there are mods which have no author anymore and there we need someone who's taking care of this, but active developed mods should be maintained by the authors.
And Dan you highly misjudge and misunderstand 7H. 7th Heaven is just a tool to easily install mods without going into the process of moving, decompressing, compressing and moving files back. That's its main purpose. But it also has functions, which did allow certain mixes of mods. It has also functions, which allow mods which are hardly realizable with the ordinary tools. You should really have given it a chance. I also think that your new mod manger will be hijacked by 7th Heaven, and we control your mod manager through it, it has the functions for this.
Though, this really doesn't matter at all anymore, because I think quantumpencil's Sister Ray will replace any modmanager in the future. It changes moding the game into an entirely new level. But I guess we need than a real modmanager to sort and handle mods like MO for the Bethesda games.
