Please add a link back to the original email into the zoho projects gmail integration so that once the task is completed the relevant email can be easily found and replied to to update the client of the progress/completion or ask for additional information.

Todoist does this brilliantly in their gmail integration and I used their task management because of this seamless email > task > email with a single click without leaving  your inbox feature. I am now trying hard to migrate my businesses to using the Zoho apps but its really laking the seamless integration todoist boasts.
