chrome extension improvement

Our company developed an Application Tracking System (ATS). This SaaS services allows HR and recruitment departments/companies manage candidates and job offers. We created a chrome extensions to allow importing candidates/talents/profiles from different sites. Currently we support LinkedIn but will extend it shortly, The current extension adds a button to LinkedIn profiles and parses the candidate info when clicked, then POSTs the candidate profile to our app API to save its content. That part is done and working OK. We have a first version of our plugin that you can found here : [login to view URL] We want to improve the plug in by adding some more features and messages. 1 - Provide user messages depending on the outcome of the POST to the rest API. 2 - Re-authenticate if the post fails due to authentication. 3 - Allow the user input and post comments once the candidate POST is successful. 4 - Read from the API a list of tags and allow to tag the added Candidate 5 - Post the profile image from LinkedIn to the API 6 - Support [login to view URL]: Repeat the same functionality we have for importing from Linkedin. We want to be able to also import resumes from [login to view URL] into our ATS. We will provide a more confidential document with some more technical details as well as git access to the existing version of the Chrome Extension.
