Hmm... I had known of this, but always thought it added a lot more than just the essentials. Looking at it again, apparently it does offer a minimalistic installation that only includes BGT, the fixpack, and the music fix. Not sure if it includes the widescreen mod though.
I'll download it and take a look, and maybe I'll add it to the original post as an alternative way to do this.
This is not what i would call essential mods, actually, you pretty well summarized them in your first post. BWP is more for people whom like me have played 12+ times the game, not recommended for first time players. I would not like them to miss the original experience.
Also let me make some advertisement for the other topic,
about where to find mods to complete your "essentials mods".
