IMPROVEMENT: Taking receipt pictures
Taking receipt pictures should be optimized I recommend something like Google Drive scan document feature. Because your picture is still showing in gallery and also it's impossible to crop the document which is very important given the receipts are mostly in odd sizes.
Already implemented, will be released in a new version 3.1.5
Since now you will be able to attach pictures made by camera of your phone or attach older pictures from your device.
The pictures are not saved in my phone's gallery
