- Labels for the input boxes on the popup login form
You'd need to add these on your own as we don't have an option to do this automatically. To do so, create a template override for the /modules/mod_sclogin/tmpl/login_ and add the label fields wherever you need.
- text links for the forgot password and username instead of buttons.
There are options in the SCLogin module parameters for "Show Forgot Username" and "Show Forgot Password". Simply enable those.
I hope that helps,
Alex
