Hide Placeholder Block

This morning as I was working on a course, I thought about how much I would love to hide a block for future use. That way, when I have the content, I can update the course without forgetting what I wanted to include. Basically a placeholder that is hidden, so I can publish the course without the end user seeing it.

Right now, the course can live without the content, however, it would be an impactful iteration to be able to include a video. I currently have a video block with the stock video sitting there as a placeholder, waiting to be updated. If I could hide this block, as you would a presentation slide (think PPT), and publish the course with it hidden, I could then go back when I have the filmed content and easily update the course and republish it. 

I know it seems as though I could leave this as an editing note on my storyboard, or set a reminder, but it would help a lot in the development phase too as ideas are swirling around of how I would like to best present the information. I sometimes test different types of blocks to see how they work with the content I am including, and when I go to preview each different block with the same content is there. This would be a nice way to compare the flow of information without having to have two blocks with the same information. You could just view one at a time and choose the one you prefer, if you were able to hide one.

Hopefully, this may be considered for future development!
