easily switch between content types (text-only, text with full width image, etc..)
if I create a text-only item with links and I want to add an image later, i have to create a new item, copy the text and add links again
At the moment there isn't any easy way to do this I'm afraid. I'm really sorry about that.
To make things a bit quicker for you, you can click on the <source> button in the editor and copy and paste the content (with links) straight into another editable area. Just use Ctrl+C and Ctrl+V to copy and paste.
Hope that could work for you!
