The capture previews that CleanShot X provides are a useful part of my workflow. I often capture a screenshot or recording a bit in advance of needing to add it as, say, an attachment. The preview icons float off to the right of my screen, generally out of the way. As soon as I need them, I can annotate, drag-n-drop, etc.
Sometimes, however, they do get in the way. But I'm not ready to dismiss them and I don't want to save them off to some folder buried in my file system.
To temporarily slide the capture previews down off the screen, I can hit the
shortcut Ctrl+Opt+Cmd+H. The arrow at the butto of the screen can be clicked
to unhide them, or I can hit the same shortcut sequence to reveal them.
