Feature: sync setting/keybinding/plugin/snippet...
Open sublime on any computer I come across, login to sublime acc (maybe). All my setting/plugin/snippet will be sync to the current computer. It will save lots of time setting up everything all over again.
As an alternative to sublimall, I personally just have any of my important dotfiles (.vimrc, .vim folder, .bashrc, .config folder, whatnot) in a git repository.
