Attachment option: to attach a copy for the bill
When working in big groups and specially with some people in the group who you do not know too well, it would be good to have a option where in while entering the amount there is an upload bill option. With this all people in the group can see where the money was spent and is the claim genuine.
This feature is already available on both iOS and Android.
While adding a bill, look for a camera icon or receipt option, this allows you to take a picture of the bill and attach it along with the transaction. This picture is then permanently recorded with the expense, and is available to all users involved in the expense.
Not sure about this idea.can we have attachment option for new activity creation.just small image of the Bill/receipt.so that it will be something make useful.
