Why doesn't Theia support filesystem-level Undo/Redo like VS Code?

[YueCHEN195]

Hi all — I noticed Theia provides editor-level undo/redo via Monaco, but I couldn’t find a filesystem-level undo/redo feature (for create/delete/move/rename/write operations) similar to VS Code. Is there a reason this wasn’t implemented (design/technical trade-offs)? Are there any plans or roadmap items to add filesystem undo/redo in Theia? Thanks!

Theia's FileService is based on VS Code code before filesystem undo/redo was added (Nov 2020, issues #9390/#111015). VS Code's workingCopyFileService wraps file ops with IFileOperationUndoRedoInfo for undo support. To add this, Theia would need to port the workingCopyFileService pattern and integrate it with the existing UndoRedoService. Workaround: use git or file history for recovery.

Thanks, that succinctly sums it up. Our initial implementation predates the feature in VSCode and so far, no one has prioritized the feature enough to contribute it to the code base. I don't think we even have a feature request for this yet. @YueCHEN195 Feel free to create one. As always, PRs are welcome :)
