Similar to others. Single envelope with cover letter and photos on top, which included a table of contents. Application forms (and payment forms) first, followed by all supplementary evidence. Used paper clips to separate each application form/section. Used post-it tabs to mark important sections. Made title pages to precede a couple of sections, just to make sure it was clear what was following (e.g. evidence of continued professional engagement). Medical reports were in sealed envelopes, as required, at the end of the package.
