I just had an idea that I think could really enhance this plugin further.
Part A): It would be great if in the Admin area, on the Widgets page, if there could be a Edit link within the Content Block widget that when clicked would take the user to the edit screen for the selected post (ie, Content Block).
Part B): In the same vein, it could also be helpful if it were possible to display an Edit link for the respective post (Content Block) when the widget Content Block is displayed on the public website (only when the user is logged in). This would be similar to how things function when the user is logged in and typically sees Edit links for Posts and Pages. I would imagine that some users might not want the Edit links displayed (for example, if displaying them causes display issues), so it would probably be good to have an option to disable this feature as well.
The advantage of having Edit links available in the above ways is that it simplifies things for users who might not fully understand the connections between content blocks, widgets and where the content is ultimately displayed.
Thanks for your consideration!
