This simple addition would be very nice so we (clients) can see what version we are on.
My recommendation would be in the creation of the .htaccess file, right below this text:
# This file was generated by Magic SEO URL for ZenCart - http://www.magic-seo-url.com/zencart/
# 2006 - 2007, (c) Jiri Stavinoha
put # Version 1.###
This way we would know if we need to request an upgrade or not.
