Used this module often, as many others before and after me. Great functionality. But wanting to keep my warnings on 0, this module has 5 warnings that can and should be taken care of. So I set out to that task. Got to the root-cause of the warnings: DS_CheckForSetup and improved this not only removing the warnings, but also lots of techdebt:

• started with 7 decisions and 14 activities and 5 CW0040 warnings, ended with 4 decisions and 8 activities and 0 warnings
• Fix a hazard: when Encryptionkey is empty, it only warned the user to first set a value to this constant. Now it gives that message in the snippet itself, preventing the user to still use this module and ignore the warning.
• The above fix also removed one CW0040 warning.
• removed 3 CW0040 warnings caused by unneccessary call-page-activity. Removed the 3 activities;
• removed the last CW0040 warning caused by refresh-client of activity Create EmailTemplate;
• improved the structure by creating EmailSettings_FetchOrCreate. Replaced DS_GetEmailSettings with this logic, only using DS_ when it was called as datasource, and calling the fetchorcreate in the other occurences;
• reduced the two calls to CountNrOfTemplates to only one;
• removed superfluous decision at the end of the happy-flow;
• decision with message '>0' actually compared to >1; changed the message to 'EmailTemplateCount > 1';

Hope you like it, agree with me that this is an improvement and that you will adopt these changes into a new version 11.0.1 or 11.1.0.
