Although its rather minor, I also must agree that I personally prefer it when PAs dont use Vendor named folders. Even if you do remember the vendors name, IMO its just an extra folder you dont really need, it breaks consistency and slows you down a tiny bit, (hardly the end of the world though).
BUT! (and in defence of PAs that still do this) I think it comes from the old standard that was often used in poser runtimes, as Ive noticed that PAs who have been around the longest, tend to be the ones who do vendor named folders the most. So my theory is that they are (in there own way) being consistant with the way they have always done it in the past. I guess Its Daz who changed the standard with the /People/Genesis/Clothing path.
Still, there should probably be one standard that everyone should stick to though.
And yes, when people dont use any sort of conventional folder structure, that it can be truely infurating to have to go digging for something, - or have to move it to the correct path manually to tidy up.
I dont know how this gets past QA , Daz should really clamp down on it.
