You don't really need multiple cursors in vim. Visual mode is much more powerful than dropping a bunch of cursors at the right places in lines or blocks of text, and if that's not enough, :s commands handle pretty much every usecase. If you're _still_ unsatisfied and want some corner case that's best satisfied by multiple cursors, then you can use the plugin. I installed it thinking it might be useful, but I still haven't found a use case where I prefer multiple cursors to visual mode or ex commands.
