Creators should be able to edit their post/submission multiple times before it's finally submitted. Creators don't have to be glued on to the screen for the complete process anymore, instead they can save draft and edit it later.

Yeah even though most creators only need to use a minimum of 2 sections, most of the time if your creating a big update or a whole new submission, and MCPEDL times out on you, you have to store a minimum of 4-6 sections in a word document such as a .txt file or google docs, or of course Microsoft cringe ugly word app.
