This isn't super-important, but I noticed that when you create a Bug thread, you can attach a screenshot... but there's no way to unattach it before making the thread without replacing it with another screenshot, and no way to unattach it after the thread is made, period. This particularly caught my attention since the screenshot I used (saving the image of the javascript of an island) turned out all black, not what I intended. For users like me whose screenshots turn out wrong, or for those who attach the wrong screenshot but don't realize it until after submission, I think being able to unattach screenshots would be useful, albeit minor.
