When a user creates/proxy votes an Idea from Salesforce (support case, etc.), the list of those Ideas are captured in Salesforce, including a 'Del' function. Clicking to 'delete' the idea only deletes it from the list in Salesforce, not in Aha (portal or workspace), so it's misleading.
The idea is to provide only View (and/or Edit) functions rather than Del within the Salesforce idea list interface.
We upgraded the Ideas Advanced integration with Salesforce to work seamlessly in the Lightning interface. You can capture detailed feedback with dynamic forms, too.
With this upgrade, we changed the "Delete" copy to "Unlink" to make it more clear.
