Is there a reason why these enhancements you'd like to deploy should be done before the game's release?
Most game reviews (which are a large influence on most people's purchase decisions) will be based on the released version. Presumably more features / content from the start will help with initial sales, and a better editor should result in more user made content.
Post in the Beyond Divinity forum for specific issues, but I had no serious problems with the unpatched original release, let alone the Anthology version.
