Steps to reproduce the problem:
1. make a really good theme idea
2. put alot of work into it
3. close the page accidentally

What is the expected behavior?
to not be able to recover my work

What went wrong?
I closed my theme creator accidentally, leading to me not being able to recover it but i installed the final version and it is currently on my desktop right now. I feel hopeless and angry since i saved it but can't do crap. I would suggest a way to open the theme file on your desktop to avoid situations like these...

Did this work before? N/A 

Chrome version: 71.0.3578.98  Channel: stable
OS Version: 10.0
Flash Version: 

add a way to open up a file of your theme saves (the ones that you have packed and installed) so we can avoid situations like these.
