AI: zed removes all AI changes when editing a message with no checkpoints consideration #39997
Description
Summary
If you edit a message all AI changes will be lost, initially I though this is a design decision,
But know I noticed that if lets say you send 5 messages and with each message there was changes, and you edit the 5th one
I would expect that only the changes between the 4th and 5th messages will be removed, but instead all changes are removed
I'm not sure whats a good solution for this, maybe add a checkpoint after each user prompt but that might break workflows that expected that all their changes are reversible, I guess the best way would be to be able to reverse each change individually and the changes are stacked on each other, so u can undo 5th change 4th change , undoing 1st change should also undo the changes on top of it
The current workaround is to remember to use "Keep all" but in practice its not always obvious that you want to keep the changes yet

The way checkpointing works is definitely something we want to revisit as we work on the panel, as you say, it's not super obvious how...

The way checkpoints work in RooCode and Copilot is way better than Zed; you can go back to specific points.
At the very least, before reverting the checkpoints; Zed would show you a snippet of your prompts and the work that will be undone, like:
"You are about to roll back changes from:
or better yet; have a revertible check point after every change like Roo and Copilot
