it is annoying to have to save your lesson each time you close a window - how about an auto save that you can activate to deactivate at your own discretion?
I agree!!! asked for something like this several years ago. I would frequently add or edit several lessons, thought I'd save them, but couldn't leave the page because I forgot to save one. I would scroll and look and frequently could not find the lesson I had edited and would have to leave and lose it. It is why I went to planbook.com . I am back looking at planbookedu because it is easier to move whole days around than planbook.com, but I was reminded of this old problem as soon as I started working again. I may go back to planbook.com. Not sure yet.
If there is an autosave...can there also be an undo option (similar to google docs) in case you make a mistake?
I loved the post, keep posting interesting posts. I will be a regular reader...
