I've worked on some layout re-ordering to alleviate some of the pain of the current experience.

Read mode

Captions read mode is fine.

For Depicts/other statements, there are a few changes that need to be made:

• Depicted items label text should wrap, so it doesn't run into the prominent button
• Q item link is shown below the Depicted item label (to also prevent overlapping text)
• Smaller font: 14pt for label and prominent button - the text looks heavy-handed otherwise

Edit mode

For captions, there is one small adjustment I've talked about on a previous ticket (can't find it at the moment), where the trashcan should appear above the input line (on the same row as the language dropdown). This not only is in line with the current implementation of Captions on Upload Wizard, but it also gives a little more length to the input field here.

For Depicts/other statements, “Publish/cancel” button moves to the bottom to match captions, giving the statement label more room. In another ticket (T218951) we had been discussing moving the Captions Publish/cancel button to the top to match Statements, but we're doing the opposite instead because it works better on mobile to have Publish/cancel at the bottom and we want to keep things as consistent as possible.
