Pitch: what problem are you trying to solve?

It would be cool to keep track of the date/time when each account was last reconciled.

Describe your ideal solution to this problem

When reconciliation is successfully completed, after cleared transactions are marked as "reconciled", the account reconciliation date would be recorded. The last reconciliation timestamp would be displayed in the UI for each particular account.
