Can you click on a created task in Things and get back to the mail message in the iOS Mail app (as opposed to just seeing a copy of the message as text in the todo app the way most todo apps handle email->task connections)?
The iPad version allows you to create tasks truly linked to emails but the iPhone version doesnt let you create them you can only open them (from what I can find, hopefully I’m wrong as I’ve been looking for this feature for YEARS and would love to make this app home)
