Fuzzy matching vs Tab completion
The animated gifs (which are for version 1) implied that the plugin supports tab completion. At first I was disapointed that this wasn't present in version 2 - until I realised how totally cool the fuzzy matching is.
With fuzzy matching, you only need to type a few letters of the filename you want - and it will find it for you. If you type 'js' and only have one file that has the letters 'js' in it - you've got it.
Here's an example. If you're working on a search module for instance, using a framework that requires all your files to start with the module name, you have the following list of files :
To get a the file "special_search_ui.js" with tab completion, you'd type : s<TAB>ui<TAB>j<TAB><CR> (or something similar)
With fuzzy matching, you only need to type : js<CR>
