Clipboard adjustments

The Clipboard feature needs to be adjusted to make it more clear to users.
Feedback is missing, actions are not clear enough, and usage needs some guidance to be executed.

To be defined:

• would it be possible to use the clipboard only for moving content, and let Copy action as a toolbar action with a paste directly in the current container?
• the Add to Clipboard / Clipboard icon should be updated according to the previous decision: the clipboard icon or the move icon.
