Great summaries

I like the concept and saves lots of time. Only issue is that History doesn’t work for me so once I leave a summary that is created, I’m unable to go back to it and view past summarizations. Fix this and I’ll be a happy camper!
Developer Response
Sorry for your experience. Just a quick note: for history to appear, you need to save summary first. If it’s still buggy, you can report the issue on GitHub or email me at thiennguyen-it@protonmail.com. Thank you for trying my app!
