Another thing that would be useful is for your version-control systems (git/svn etc) to be able to say precisely who made which changes. That gives you proof of who did which work. Even if your company/org does not use version control, you can use it independently as an individual, and have a complete development history of your own which documents your work. It would be harder for someone to claim your work if you have a ton of incremental check-ins and they don't.
