Quite often I'm copying and pasting email addresses into DEAR and they get added to DEAR with a space either before or after the email address. This is a pain because there are no errors thrown until I sync the data to Quickbooks and Quickbooks returns errors.
Ideally DEAR would do some validation at the time of data entry:
1) Automatically trim whitespace off an email address, or
2) Validate the email address format and give an error if there's whitespace present
The DEAR user interface makes it very difficult to tell if there's extra whitespace in a text box because of the padding you use in the HTML controls, so some extra validation here would save me from having to update customer and order records in order to fix Quickbooks sync errors.
