This is your editable copy — not the thing you send.
It holds the whole proposal: every word, your logo, the theme, palette, page shape
and any font you chose, all inside one small file — saved as .prozollo so you can tell it apart at a glance. It is ordinary JSON inside, so it still opens if you ever rename it to .json.
Keep it so you can come back and revise this proposal later, reuse it
as the starting point for the next client, or move it to another computer. Clients
never need it — send them the PDF.
Save self-opening copy writes the whole app with this proposal
already loaded. Double-click that file and your browser opens straight into the
editor — no need to open Prozollo first. It is around 1MB because the application
travels with it, and Windows will not ask which program to use.
Starting over clears the proposal in this browser. Save a working
file first if you want to keep it.
