Put together a quick mock-up.
- The black border denotes a tab. For switching between pro/con.
- I think this makes the form less daunting and shows that adding “extras” to it is not mandatory.
- De-emphasizes use of images and shows that a URL is required and that it can be a YT video as well.
- Clicking grey buttons should probably js a form field instead of a pop-up.
- Clicking submit should js the item above the form and allow quickly adding the next p/c
- Form fields for not only title and description, but grey buttons could be re-used for inline edits as well
