I'm having a hard time articulating to my team what doesn't sit right with me on this design. Here is one of our prototypes:
http://50.56.241.135/prototype/pin/feed_unsubscribe.html
For one thing, the unsubscribe link is hidden until "found". On one hand it gives the overall design a better signal-to-noise ratio by not having tons of unsubscribe links in the array. On the other hand, this option has to be discovered by the user. I feel the whole experience is a balance between sacrificing findability to sacrificing real estate.
The design also lacks the ability to unsubscribe by bulk. In any case, my gut is telling me there's a more fundamental issue with this page I can't describe.
As to the icon, it's just temporary for now. That issue is for another forum.
There are probably a lot of questions in this post, but my main one is this: When is it okay to make actions strictly visible on finding them as they are in this design?
