   1 /**
   2  * Resources
   3  *
   4  * Idea is to manage resourse used by the app.
   5  *
   6  * The original code downloaded all the resources before it renders the main window
   7  *
   8  * This is a bit annoying as although they do change quite a bit, it's not on every app start
   9  *
  10  * So the Resource fetching behaviour should be a button on the File view page
  11  * That starts the refresh of the resources.
  12  *
  13  * I'm not quite sure how we should flow this - if we do them all at once.. might be a bit of a server
  14  * overload... so sequentially may be best...
