Hi,
In addition to what Oshyan said, you can kind of see what we have in mind for the location of certain files in the Preferences. Check out the Library and Content panel. We would have a main Library type folder for certain preset stuff. This would always get searched for certain content. You can also define User Content folders. If someone were to send you a project file referencing certain items you might have in common, like an Xfrog plant library or terrain file, you could have a User Content folder pointing to the location on your hard drive that you keep that and the relevant files would be found. That's just a basic description. Essentially you have a standard location which is for Planetside provided stuff, whatever that might be, and the opportunity to define other places to be searched for project resources. All the stuff in the preferences works, but it isn't yet hooked up to into the file loading stuff on what you might call the project side of things.
This stuff still does require that you put things in certain folders and doesn't help with locating files which are moved willy-nilly. We could do that on the Mac, but I think it would be more difficult to do on Windows and then to store things in project files so that file references are at least somewhat meaningful cross platform is something else again. Not insurmountable, but not super easy either.
All this Library and Content stuff is kind of the base level of the functionality we envisage. At some point we will have a browseable Library and whatnot, but what is represented in the Preferences is the lowest level of this future system. The folders you define in the Preferences would be searched for items to be place in a Library UI, for example.
