Cursor IDE
Describe the Bug
When planning changes, I find it extremely frustrating that Cursor does not version plans. This makes it difficult to deal with seeing what changed whenever a Cursor agent updates a plan. It also is extremely frustrating when Cursor removes something important because it took something the user asked for too far. The user has to tell Cursor to redo work it already did, and pay accordingly, because the user cannot revert changes.
Steps to Reproduce
Use planning mode, tell Cursor to do stuff. In my particular use case I asked Cursor to remove code in the plan that already existed in source files. Cursor removed that code but also removed code for which no source files existed and I had to ask Cursor to regenerate something that it already produced but then removed.
Expected Behavior
- I did not expect Cursor to remove code for which source files did not exist.
- I did not expect Cursor to not be able to revert the plan to the older version that existed with the code it generated and added to the plan.
- I expected Cursor to remove only code for which referenced source files actually existed.
- I expected Cursor to show me what changed from the prior plan to the current one exactly as it already does for source files under version control even when those source files have uncommitted changes.
