I think all Google services are kinda treasure for freelancers. I also use No Kahuna for project management. Just because it's the simplest tool. I got used to it very quickly and for general projects (without much specified branches) - it's the best! I also use different file-sharing services to store and share my files. But very often it's useful to search smth on those services too (but on those which have this option and alas there are only few of them).
The best decision for that, which i found was FileTram. It's kinda file-sharing search engine, 'cause it indexes files posted at most of big file-sharing services and when you are searching on it, you can find appropriate files on all of those services! Once, i was looking up for a book and found it only there.
