With cursor you get reasonably flexible control at many levels. You can have it only suggest changes that you have to apply manually or you can have it make automatic changes with various ways to review, change, reject or accept. I usually have the changes made automatically but don’t accept the changes automatically. Cursor has a UI that lets you review each edit individually, for the whole file or all files. Depending on the situation I will use whichever level is appropriate. The UI also allows you to revert changes or you can ask the AI to undo or rework a change that you just approved so there’s plenty of ways to do large changes without giving up control. There’s also a stop button you can use to interrupt mid-stream if the work it’s doing isn’t what you want. It isn’t flawless but I haven’t found myself in a corner where I couldn’t get back to a happy path.
