I have multiple accounts in my Skrooge sessions, some are mine (individual), some are from my partner (individual) and some are couple accounts.
I am trying to distinguish expense by person in the account menu.

As of now, I mainly just rename each account with a "prefix" in the name to facilitate the identification of each account.

Is there a better way to handle this in Skrooge?

Yes, you can add a property "Who" on the account (like for all objects) and add the column "Who" in the table with the contextual menu on the header.

Thank you. With your help, I understand a bit more the usefulness of the properties.

I now use it for individual transactions for credit cards that I group by statement.

My example:

I now use the property "Relevé" (statement).
After selecting all transactions from a statement, i just add the value YYYY-Month_NumberFIRSTSMONTH (2019-01_JAN). It help me to organize my different transactions.
