Skuidify Salesforce Content Libraries - subscribing

I’m looking to Skuidify the Content details page in Salesforce CRM Content. The current Content details page (in native Salesforce) has the capability to subscribe to various things (Tags, Document, Author, Library, etc…). Has anyone Skuidified this page and if so how did you keep or replicate the subscribe functionality (you can subscribe by clicking on the heart next to an item on the screen shot below)? Thanks
