We had Infopath previous which allowed us to paste the form in the notification email as a pdf for quick review. Given that the email link directs users straight to the approval form without viewing the document that they are approving, this is a necessary feature!
Otherwise our team members are having to click the link (one click) which takes them to the approval form which they then have to click a link (one click) to see the form they are being asked to approve and then having to click back or navigate back to the email to approve. (one click... a total of 3 clicks)
Ideally the workflow is:
1) Email received with full form and can approve or reject with comments from email (one click solution)
if not then
1a) email received with full form and routed to approval form (one click) to approve or reject (one click.. total of 2 clicks)
1b) email received and routed to form (one click) to approve or reject from that form (one click... total of 2 clicks) .... NOT rerouted to the approval/reject form.
