Add sections to "Files" stage of the wizard
Add upload sections to the "Files", "Preview", and "Final proof" pages of the wizard. The sections will be entitled: Manuscript file Figures and tables Supplementary files
The design for the upload page is here: https://invis.io/8UR78IFPR29#/351342968_B3-Sub-Wizard_Files1
The design for the preview page is here: https://invis.io/84R78LIDZNW#/351342964_C1-Submitter-Preview_1
The design of the final proof page is here: https://invis.io/S7R79GK6FZH#/351960036_C4-Finalproof-2
Additionally, it seemed like viewers were consistently struggling to assess the figures and files on the Preview page. And when they were seen larger (as on the submission confirmation page), it was more graspable. Consider making the files section on the Preview page only one column wide, with a bigger image and longer text length. The designs do not show this option.
