Thanks for your work!
Hi SBA, thanks for your hard work on Planned features! I see that you have been busy on it for much of the evening.
A quick glance at the recent changes log shows a lot of activity. You might find it easier to use the Preview tab at the top of the editor, or the "Show Preview" button found at the bottom of the text editor as you edit. You will see exactly what your changes will look like, without saving them forever to the server! It might save a little space in the long run.
