Suggestions to improve Custom Review Email Editor

I'd like to suggest a couple improvements to the custom email review editor to make it more consistent.

There are a few odd inconsistencies for styling:

1) Rating Block—Please add the ability to adjust the border radius on the button in the Rating block (this is possible in the Review Other Products and Store Review block).

2) Review Other Products block—Please add the ability to adjust the block title heading (h1/h2/etc). Right now, it's hard coded and does not match the default headings—for example, I can't make the font size for the Review Products block consistent with the h1/h2 headings in the Hello block or the Write a Store Review block.
