Something I realized today: I can use "Ends With" as a Visibility Rule filter but not as a constraint or choice filter. This causes issues.
For example, if I want to hide Canadian people from seeing a form option, I can set a visibility rule for "Ends With .ca" but I can't make a smart list for "Ends with .ca" Using a "Contains" isn't a good choice since .ca (or anything similar, but using this as a Case In Point) isn't unique and is quite common.
I really do like the "Ends With" criteria so I propose putting it in the Constraint / Choice option.
