- Move all utilities to a separate clients.py module. Tests too. - Use fewer custom template tags. Actually only one tag is really required. Keeping custom tags minimal is a goal. - Merge the methods to generate app store URLs. - Implement a validator for validating client information and use that instead of enums. - Internationalize the text on template page. - Add missing RPM package case. - Cleanup CSS. Remove unused styles, minimize the styles set. Signed-off-by: Sunil Mohan Adapa <sunil@medhas.org> Reviewed-by: James Valleroy <jvalleroy@mailbox.org>
