Some Ember.js Javascript Work -- 2

I have an application that allows the user to take measurements (lengths, areas, etc) of images on documents which are loaded into the app. The application is written in Ember.js which also uses the [login to view URL] library and need the following done, for an Ember.js ninja these will be very easy, the tasks start easy and get more difficult (and pay more) as you go through them, the tasks are, for a total of $132: - $11 - Bypass the elevation areas - $22 - Make it so if they click approved or another tab, they can still start over if they wish to - $22 - Make it only ask window specifications once - $22 - Have the change file feature on the mapper area - $55 - Have a files area where previously uploaded files appear If you're 100% new to Ember.js and while new to the application the tasks will seem larger than they are but all of the are relatively small tasks - soon you'll know both Ember.js and the app like the back of your hand!! Also so I know you've read this properly please tell me your favourite animal in your proposal. You will be given a link to the repository where the app is on GitHub and will submit your work via pull-requests - one pull request for each task. I will review your work and release each milestone once I've verified the task to be complete. If you do well you will have a never-ending amount of work from me!! :) Ember.js: [login to view URL] [login to view URL]: [login to view URL]
