I consider the actual Git Hub version final. Resume of the last updates:
optional hide on checkout pages (login.php, checkout_shipping.php, checkout_payment.phpheckout_confirmation.php and checkout_success)
select on which pages to hide each area by checkbox list
select each group to hide (navbar, header area, boxes, footer and footer suffix
define content width if side columns are hidden, allows to control if main content gets stretched or keeps withe space for side columns
optional customized list of header modules to keep showing if header area is hidden.
Update from previous versions: uninstall ht module, replace ht module, reinstall ht module.
I'll keep it for around one week without touching. Please try and let me know any issues.
Then it will be published.
If I find time Ill try to go for the version to control each individual module.
