With DragDropr Chrome extension you can edit any page created with DragDropr (That is because it adds a peace of code for extension to recognize it.)
You'll see a notification sign near the icon showing that this page is available for editing, like this:
To edit the page just click on the extension icon.
Then click on EDIT PAGE to open the DragDropr editor, pop up window will appear.
As soon as you've finished editing, click on Save button to apply the changes.
Voila! Your changes are applied to a live page now:)
