I've seen a few examples of this, and sometimes it was an improvement and other times it wasn't. It's one possible solution to a problem, so without knowing your problem in detail, neither me nor anyone else is going to be able to give you a definitive answer.
Adding an extra step will clean up your page, but it will result in fewer people using the actions that if they weren't an additional step away. Whether the overall impact is an improvement is something that you will have to test with your target audience or customers to know for sure.
That said, the button itself looks nicely discoverable in the navbar, and the way that you are displaying the actions (presumably when the button is clicked/tapped) is clean.
Once you do some usability testing on this (which I really hope you do), I would love you to come back and let us know what you discovered in the process.
