Go to Message Filters-> New -> In the criteria line, where you need to give the criteria, nothing gets suggested when I enter some text Actual results: Currently nothing gets suggested. If I want to enter email address, then I need to remember the email address. Expected results: The criteria box where text is entered should suggest email addresses. Else users will have to copy/paste the email address.
You can use the menuitem Message -> Create filter from message and then you get some values prefilled.
