This feature was crucial. Previously, after the agent made multiple file edits, you could test and revert the code at any specific step. Now, to achieve the same, you have to manually insert a message to create a checkpoint — and even then, you can’t go back to any point that was after that message you inserted.
Trial and error is crucial and fundamental when coding with AI and not having this feature makes the workflow very inefficient. And it’s not something you can easily work around with Git, since the agent often makes multiple changes in a row across different files. You can’t reasonably commit after every file edit just to simulate this functionality.
Please restore the option of automatically created checkpoints before every file edit. The infrastructure clearly still exists (e.g., the small “+” buttons that used to allow message insertion), so re-enabling this would greatly improve the coding experience without requiring major changes.
