It would be very useful that Sketchup styles could be assigned by object rather than globally to all objects in a scene.
Sketchup styles are very powerful and, in combination with layers, they can do a lot, however the complexity of what we could achieve is limited as you cannot mix styles easily and, to achieve special presentations you have to rely on compositing scenes in either Layout (stacking viewports), Image Editors like Photoshop (exporting images), Illustrator or similar software (exporting pdf/raster images) or CAD (exporting DWG/DXF).
Either of these software packages has different possibilities and limitations but you have to be a very advanced user of Sketchup, Layout and each of the packages you choose, to be able to achieve great results.
In most scenarios it isn’t possible to preview the final result and you will require trial and error approach that will get you jumping from Sketchup/Layout and/or other software to get desired results.
If we could combine different Styles for each object in Sketchup directly in Sketchup viewport, we would be able to create stunning or technical presentations very fast with a huge level of configuration.
A simple example:
