Yup. It’s there in the Revo Manager. A number of addons are available this way. You can browse the add-on repository, get the packages, and install them all inside the Manager. There’s an option to have a license screen, get user options, and view the readme.txt file during the install.
Remember that this is still an alpha release, though, so there may still be a few kinks to work out. In fact, we could definitely use some more testers.
