Could you build this?
No Building a custom, native non-WebView desktop Markdown editor in Rust using Slint requires deep systems programming, custom text layout rendering, and complex native document synchronization.
What it would actually take: Built with Rust and the Slint UI toolkit, this requires writing native text layout and editing components, an integrated syntax highlighter (e.g. syntect), and custom renderers for KaTeX math and Mermaid diagrams directly to native vector graphics canvases without relying on Chromium/Blink engines. Writing a synchronized split view with non-HTML DOM diffing requires significant GUI systems and compiler/parser expertise.
