Beneficiaries and Tags for easy classification.
With accounts and subaccounts, I know that I spent $1,000 on personal expenses in a year, but not where I spent it.
I can enter the name of the shopping center in the description field, but I could write it differently: "shopping center," "Shopping Center," "SC," etc.
An optional "Beneficiaries" field would be useful for recording transactions. A supplier could also be included here, since they are included in the Business module.
Obviously, associating Tags would further facilitate the classification of transactions.
