Save drafts or 'Download as' option when creating a new topic/idea.

I’m adding my vote here as I just lost an idea that I spent 15-20 minutes writing (for this community!)

I’d written the idea and when I hit submit I got ‘whoops we can’t find that page’ message. When I went back, my idea had disappeared. 

I like the way jive does this on replies. It automatically saves your draft as you are typing, and when you navigate away and come back, it gives you an option to load it back if you like

I have also just lost about an hour’s work creating a community conversation b/c my browser crashed.  In an effort to not demotivate people from creating community posts that aren’t Admins, this is a huge need.

I have power users asking for this as they often create a lot of content, then risk loosing it.
