Every transaction is linked to a concrete account.
Management of accounts is done in Settings.
By default, three accounts are created, and you can change the name, colour, description, currency or initial value in each account. If you have purchased the premium version of Wallet, you can add an unlimited number of additional accounts.
The initial value of the account may be negative, just subtract a specific amount from zero (eg. 0-100 = -100)
Accounts with current balances are also displayed in the widget on the desktop.
