| ### Optional transaction ordering | ||
|
|
||
| The module supports optional transaction dependencies through a prerequisite mechanism. When creating a transaction, signers can specify that it should only execute after a specific previous transaction has completed. |

Have you needed this in the past, for situations that a multi-send wouldn't solve?

Was OOO for a few weeks, coming back to this.
We have in the past had scenarios where several transactions need to be executed in a specific order (ie. add a new module, then upgrade chain A, then upgrade chain B, then remove an old module).
That's not to say we couldn't handle this mostly with ops, but the feature is a pretty small diff and gives the module more potential value as a public good by preserving the ability to enforce ordering as with the base GnosisSafe.
