It is really really difficult to keep up with comments and discussions on Wrike - they happen in multiple places depending on the user's understanding of Wrike and preferences. It could be on a proof, task, subtask, or the top level of a project. If they don't at mention the appropriate people comments get lost or you have to hunt for responses and it's really a time drain.
There needs to be a way to centralize discussions using some kind of thread feature so we can easily follow along with a discussion.
Also, people should be able to use a single click to opt-in and opt-out of notifications to updates for that discussion.
