I have these three questions:
1. What is the purpose of the "Add Contact" functionality?
I know this is a way to send money to an unregistered account but is there any other situation that I might want to use it for?
2. The "Toggle Approval" button has three options: positive, negative and neutral. What is the purpose of the negative option? When I perform my vote using the "Update Vote" functionality, only positive votes show up as a result and negative ones seem to be ignored. If that's the case - what is the purpose of the negative approval option?
3. I understand that the "Toggle Approval" is for voting for delegates, both active and stand-by. But in the GUI the toggle button is also used in the context of non-delegate accounts. What is the reason for this? Why might I want to approve of someone who is not a delegate?
