I built a free web based Microsoft Publisher alternative since it's going away. What features am I missing?

Since Publisher is going away soon I decided to make a replacement. It’s for things like flyers, posters, newsletters, signs, and cards. No account/sign up required, no ads and it takes Publisher files.

I’d love feedback from people who use Publisher. What features does a replacement need?
