At the moment if you want to add an element in the library if the object in question was not created by hand, you need first to make a screeshot and then add the element. This can be relatively time consuming if you want to bulk create them, since making a screeshoot is a three step process (take screenshot -> Select export -> copy )

An alternative would be to either or both:
* add an element directly as an image by selecting a portion of the document
* or by adding an instant snapshot feature to copy the area into the clipboard without any additional steps.

A nice to have would also be to have a basic image modification to change the colours say black to red etc. and copy and paste if using a keyboard.
