The software is missing a few extremely important thing, the biggest being a way to present the information. You need to use layout, which is extremely slow and doesn't handle the large models. Line weights are flat, it doesn't produce different hatching, so you also need to buy scalp. You need to be conscious to put everything on the correct layer (and the layering system is preset and complicated. Any freestyle modelling isn't captured by their layering system, and preset scene tabs, so unless you use their exact library parts then the use of the model becomes very complicated and frustrating. It's an easy program to learn but not an easy program to manage. The biggest issue is it's only have a program, and reply's on Layout to present the documentation. And there's nothing smart about Layout. It's like doing documentation in Photoshop. Plus Spec needs it's own layout program, which has proper layering options, linetypes, importing functions and exporting functions to DWG. Dimensioning in Layout... everyone knows how bad that is. I tried linking the sketchup plusspec model to Revit to dimension and note in ICF format and add hatches and be able to communicate with consultants with 2d CAD or a revit model. But that's another program to buy and it's a dumb work around.

Basically the plugin is a good idea but it's hopeless in the real world without a proper layout program. It's not even 1/3 of a program, you still need sketchup and you still need shitty layout. $1000 for 1/3 of a program, at least with Revit you get a full program for $3000. Oh yeah you need to buy scalp to hatch as well. It's 1/4 of a program.
