This is not a big issue but it would be good to know how to increase the leading for heading size h6 as I'm using it for image captions and some of them go to two lines or more. See http://www.jackmartinleith.com.
I've looked at all 29 pages of support requests and it doesn't look like this has already been addressed.
As others have rightly said, your service is outstanding. Thank you, and warm wishes from Bristol UK.
