LinkedIns CV:s are ok:ish in design so if you can make a design that surpass theirs I'll give it a try. :)
There is a long and deep history of LinkedIn related chrome extensions that I won't get into. Many are a violation of LI's TOS. Most have to do with Lead sourcing for sales organizations. A lot of LI information ends up getting resold on grey market sites. Just don't do it. The convenience isn't worth it.
