Evaluating Umbraco v7 Plugin

We have an Umbraco v7 plugin that takes news articles from an API and adds them to the site. The majority of the task is to test, evaluate and possibly debug the plugin. The plugin has been tested by its original developer and by an external 3rd party, so we are not aware of any bugs. We would require proof of the testing, but this could just be a screen grab video of the freelancer doing the tests. What we're after is the testing, however also a review, by a very experienced Umbraco developer, of the functionality, code and concepts of the plugin. We wish to make the plugin very easy to use. We require a brief discussion and summary document commenting on what could be done differently. Required minor "edits" and "additions" are: • Removal of the option to select the Sync period - this needs to be forced to be 1 hour (Feature Removal) • Display of the Last Sync Date/Time Information (Feature Addition) • Display and editing of API Key (Feature Addition) Testing Functionality • Installation with API Key • Select Feed and import articles • Publish/Unpublish in Umbraco is transferred to Feeds • Publish/Unpublish in Feeds is transferred to Umbraco • Removing articles in Feeds is transferred to Umbraco • Adding articles in Feeds is transferred to Umbraco • Removing Feed settings removes all articles from Umbraco • Adding a new Feed is seen and useable within Umbraco • Auto-Sync • Manual-Sync
