Manage Finder favourites with defaults write or similar?
Some scripts for this:

https://www.jamf.com/jamf-nation/discussions/20218/the-slftool-thread (using repo below, I think)


And there is a relevant github that can manage these preferences as well:

[Edit: Seems like, due to a change with sfltool in 10.3, people are using this: https://github.com/robperc/FinderSidebarEditor ]
