The Account Picker

This account picker is sort of broken. The idea is that you can select an existing account from the tree display, or enter information for a new account in the boxes below. However, right now it's possible to do Very Bad things like specify a subaccount of an existing account with a type that's not compatible with the parent. As soon as I figure out how I want this dialog to work I'll fix it. I have tested out the worst things that you can do and nothing terrible happens, except your account tree might be in a state that you could never have created through the GUI (a Credit Card account as a child of a Bank account, for example). Don't do that. I'll fix it Real Soon.
