Not a bad idea to list key threads that explain stuff, but there is always the FAQ and the user manual that covers a lot. And compiling the list involves quite some work. and, as slimpy says, there is a search available in the top right corner on the webpage - even if it is, well, hmm, maybe not always perfect. But then you can always use alternative search engines to do a site search / advanced search, e.g. Google site search to play with search parameters on the SH3D site:

[font=courier new]window properties site:sweethome3d.com[/font]
https://www.google.no/search?num=50&q=w ... home3d.com

For imports from the 3D warehouse, if .kmz is not available, there is often also the unzipped .dae (Collada) format that also can be imported directly. I fear auto-converting or copying converted files would not only be a never-ending task, but more important, it is probably not possible because of the copyright implications.
