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...
