Similar to excel, it would be really nice to have the list lines numbered. I frequently go back and forth between Excel and Aha reports to cross reference data and make updates to Aha fields. However, it is easy to get lost and update the wrong line when I have to count down from the top to find Row 7 or 22 because it is not numbered by default.
If others are opposed to this, it could be a field we add to the list ourselves so not everyone is exposed to it. :)
