Documents

A "document" represents replacing a single VFX. You can create or delete documents, as well as switch between them, using the documents dialog.

Workspaces

A "workspace" is a collection of documents. When creating a new workspace (or initially opening VFXEditor), it will have a single document. A workspace also keeps track of particle and emitter renaming, model replacement, and texture replacement. Workspaces can be created, saved, and loaded using the "File" menu. Workspaces are saved as .vfxworkspace files, which is simply a ZIP file of the VFXs and textures.
