Thanks and credit should go to James for his efforts.
Please note: in order for the banner to be added to your public profile, you need to have some content in the "Bio" area (old UI) or About tab (new UI). If this area is empty, the necessary container is not generated by the site. An empty HTML comment (<!-- -->) is sufficient and prevents the need for unwanted output in your profile. This is also true for James' Church Micro Stats. This may be fixed in a later version.
Update: This should no longer be true in the new UI.
Added a configuration dialogue which allows you to select the brand displayed on the banner.
Updated branding to include the CofE levels beyond saint/5000 finds and added the secular levels.
Improved the banner tooltip formatting. It now wraps for neatness and readability.
