Yesterday, while I was trying to batch-increase frequency of reviews for a number of hot projects, it came to me how cumbersome and frustrating the process was. Go to the Projects perspective, find the project (which in my case involves going through 2-3 levels of folder hierarchy), long tap, select Review, find yourself in the Review perspective, adjust frequency, go back to Projects, find a next project and so on… It would be so much easier if sending a project to Review was done in the background without changing the perspective. That way, one could send multiple projects and then switch to Review on his or her own. I really hope OG will change that!
By the way, on the iPad I have discovered a workaround for this limitation: switch to Review, search for " " (space) in Remaining - the results will list all your projects and tasks. From there you can scroll through the list and send projects to review while staying in the same view.
