I have received several bug reports about copy paste
Copy paste curently works with ctrl+c / ctrl+v but when you paste, an element needs to be selected on the stage (it will paste after the selected element). It works also across pages
This is obviously not a nice UX, especially if the page is empty and you want to paste something. So I fixed it so that it always pastes something, event when there is no selection. But it is in grapesjs core so I did a pull request and it will take some time before it arrives in SIlex

Also sometimes the keyboard shortcuts may be bugguy depending on your browser and OS, so I also added copy / paste buttons in the UI. This will be live in Silex soonish:
