This applies to the "Where It's Going" and "Budgets" widgets on the Home page as well as budget envelopes within the Budgets section.
Clicking on a category in "Where It's Going" or "Budgets" in Home section or a budget envelope should open a floating window showing the individual transactions, both debits and credits, that make up the displayed amount for that category or envelope, also providing them with an option to view those transactions in the Transactions section.
Users often need to inspect which specific transactions are contributing to a category or budget total. Currently, this requires navigating away to the Transactions section and manually applying filters to isolate the same data. A direct drill-down would let users verify and review the underlying transactions right where they spotted the total, without breaking their flow.
This adds convenience and also supports troubleshooting, for example, quickly checking if an unexpected total is caused by a miscategorised transaction, without leaving the Home or Budgets view.
