Hey @dcoa , I'm interested in making sure this gets across the line. Is there anything blocking you or anything that you'd like a second set of eyes on?

[bradenmacdonald]

It just occurred to me that if we need a place to store uploaded static assets when they're uploaded before saving, we could potentially use StagedContent to hold the draft version of the new component. Not sure if it's a good idea or if we should just save things locally in the browser, which is another alternative.

Sorry, I have had some issues with the pc and additional tasks that slow my progress, but I will continue working on it tomorrow, most of the code is already functional but I need to change the reset logic a little bit.

Thanks @bradenmacdonald for your help giving me options for the images issue, I will start testing that.
