Currently Todo's in the summary email do not include any contextual information - for instance a Todo attached to a feature, does not include that feature name.
Often when I am writing Todo's I will assume that context, so for instance a Todo might just read "Talk to John about this". Without showing that contextual information I am unable to understand from my summary email what I need to be working on.
Attached is a screenshot that displays what this can look like for me, and I think demonstrates the issue.
Thank you for the idea. We have recently redesigned the summary email and include a link to view all to-dos. Given the new design and historical feedback in this area we are unlikely to implement this idea at this time. We hope you can understand.
