Several of us were talking and found no way to delete, or get rid of things we no longer need in our App bar, such as Release Notes. Would it be possible, without a lot of effort, to add a small trash can, or waste basket on our window, that we could drag and drop things we no longer want ? The 'can' would then be deleted completely when we took the action to "empty trash can". This would also allow us to retrieve items from there, if we felt we needed to, or if we inadvertently tossed something.
