I'm working on a little project to sync splitwise transactions to lunch money (https://github.com/daniel5151/splitwise-lunchmoney), and it'd be cool to have a credit-card style "pending/posted period" for API-imported transactions, similar to what plaid-imported transactions have.
i.e: transactions could be set to appear "pending" for a few days (e.g: while friends make quick edits), and then transition into a "posted" state.
My tool is totally workable without this feature... but form a UX perspective - it'd be a great way to visually indicate that the transaction is still "in flux"
