Add A navbar with link to open the default navigator file chooser
Add a directive to turn element into a button to open the default navigator open file dialog. Test isn't implemented since it's data is relative to the user action.
A little controller to test the filePicker directive. The on-change callback return the scope rather the file. Need to be fixed, but I don't know how right now.
Add the ability to open, create a file.
Add a file-saver directive. It's allow the user to save into a file data locally without server request. It works but not locally since chrome security rules. Idea of improvement : remove the  function.
Add a showdown filter to convert Markdown text into HTML ones.
Fix a infinity  loop when using  in an isolate scope. See issue in angular 1.2.0-rc.2 #3932
Add MathJax compilation. However it don't deal with $. Need to be fixed through the regexp in mathjax filter.
Set the less compilation with grunt.
Add css styling of main part in less.
small correction
