Installed it and played around for a bit. Nice work overall. Amp's jump mode (press `f` and elements in the buffer will be prefixed with a two character jump token) is pretty cool. Would love to see this in Vim.
The irony. Easymotion was created as a better precisejump. Precisejump was created or at least uploaded in Feb 2011.
Some other commenters in the thread have raised the point that having more supported functionality out of the box is a good selling feature. To me it seems that having it built it can (possibly) benefit from a more intentional effort to make it cohesive, whereas with many disparate plugins you have to encourage, force, or otherwise guide developers to build something that fits and behaves with the rest of the platform.
