Emacs users need performant editor with advanced undo history and scripting

The ask

Experienced developers using Emacs report dissatisfaction with its performance and interface quirks. They are actively seeking a more efficient and responsive code editing environment. A critical requirement is a sophisticated undo system that supports non-linear history, often referred to as an undo-tree. Many alternative editors either lack this feature natively or do not provide a strong enough API for users to build it. The user also specifies a preference for non-Electron based applications due to performance concerns. They require a robust scripting or plugin system to allow for deep customization. They find Vim-like editors unsuitable for their workflow.
