First, I want to say that I'm loving the site and the new (sort of) forums. Now, on to what I made the thread for; it would be great if there was a way to delete screenshots altogether instead of having to replace them. Would it be possible for this to be implemented any time in the near future?

Sorry for late reply. Added an "Visible" toggle to screenshot and preset edit form. That way you can hide it from showing up in the game / preset listing - but it won't be completely deleted.
