When we vote for an idea, we are not automatically subscribed to receive updates when the idea is commented on, accepted, or even implemented. When on the Listings pages (like this one) there is not even a button to do so.
Please add a Subscribe button so we can immediately see if we're subscribed to an idea we care about, and subscribe to it if not.

Even on the Idea's page itself, the Subscribed status is not displayed anywhere. We have to open the Options menu tucked up in the corner to see or change the Subscribed status. An obvious Subscribe button would be much better.
