@cyntss what are your thoughts on implementing the "more options" for each thumbnail. At the moment, when we click on the thumbnail, it is pinned to the top and when we click on the caret, the options appear. My question is, should we keep it as it is or should we get rid of the option of pinning to the top by 1-click and let all the options appear once the user clicks on the thumbnail (like in the picture below)? Or do you have any other ideas on how to deal with this problem?

Update: I have left the way it is, but changed the interface slightly. I am not sure if removing that feature is a good decision. This can always be changed once we decide to get rid of it.

@aniabui I agree with you and think that leaving it would be the best option for the time being. The icons look very good btw!
