Here are some screenshots and things that could/should be improved in regard to the Drag & Drop on a course page:

Text DND

• Unlike when dropping a file, there is no introductory text, perhaps "What do you want to do with this text makes sense"
• "What do you want to call this text" does not sound very good to me, especially that so far we only have a title/name for the text added as a "Page"

Prompt

• The prompt window is not standard to the new moodle dialogues
  • Buttons are too big
  • Alignment is different
  • No title bar and close button
  • The colour, size and line-hight of the text is different
• <enter> does not trigger the submit action
• Upload button should be greyed out when no title is entered

Course page

• Add text/link/file(s) here is not visible when the section is really long
• The loading icon
  • is not aligned with the text
  • is not standard to the rest of the icons
  • does not have the proper original size
• The progress bar style does not seem to match Moodle one's
• DND on the text Add text/link/file(s) here does not work, you have to drag any where else in the section
