While I agree that the TM "handles" are harder to use, it is more powerful than the app, such as Receipts2go. The reason is that theirs is a strict rectangle, while ours works on "aspect". So if you take a picture and the receipts is a trapezoid (which it often is due to lighting conditions), it will correct the aspect of the picture and turn it into a correct rectangle.
If you want you can go to Setup -> General -> Post Process Receipts and un-check that row. That will not do any processing on the picture whatsoever and what you see is what you get.
