Mike,
You can create your own interface any way you like. Just select the palettes you want to be visible In the order you want them to appear or use the Smart Workspace buttons on the top of the right panel. You can also create custom palettes with any combination of tools in them and in any order. The interface is very configurable. It can be a little bit tricky to set up for somebody who’s never done it, but we can help you with any specific questions you have.
With regard to Viewpoint and FilmPack, in my opinion there are no “significant” features in the standalone versions that are not also available as embedded features in Photolab, except perhaps for the Filmpack 5 presets. As a result I have not used the standalone versions of Viewpoint or FilmPack since Photolab 1 and uninstalled them years ago.
Sometime ago I created Photolab presets for all 82 of the Filmpack 5 film types and made them available here for all who wish to use them. See link below.
