Even with all scripts in instalation package you'd need to spend a lot of time reading manuals for them (for example motion detection has so many parameters!).
And what's even worse: somebody have to write these manuals and do whole this work to pack everything. There must be a volonteer to do so. And this must be a person who "have time to browse forum for downloading"...
No one knows all scripts, even basic, that are needed. If you like to have more scripts in instalation package, the best idea is just to select them and post here or in this thread:
