Keep Clipboard Master visible
You want Clipboard Master remaining visible after pasting?
There are two possibilities for that:
1. Pin Clipboard Master:
Press <Scroll Lock> and the Clipboard Master window will be pinned. With this the window remains visible and always on top after pasting until you unpin or close it. To activate the window just click at it or press the global shortcut Windows + V. And you can use drag & drop to paste items.
2. Paste without hiding
In the settings -> keyboard in Clipboard Master you can define the actions for <Return>, <Ins>, e.g not to close the window after pasting.
