We are trying to figure out how our service/produce could possibly integrate with Salesforce via a Salesforce app. I fully admit I am just learning Salesforce and I don't want to go down the wrong path in terms of design/planning.
Ideally, we'd want to integrate with the user's contextual workflow and not have them click on another tab when they want information from us.
Let's say I have some information that I want to show to a Chatter user - and I want them to access that information with a simple click of a button. Can an app add a button to the default Chatter page? Same goes with the Files tab?
Or, would the user/admin have to alter the page to add a button that would integrate with our service. Or, is it not possible with an app at all - and we should do it within our VisualForce page?
