Build me a native desktop app for crypto market charting that feels like a serious trading terminal.

I want it to support Binance, Bybit, Hyperliquid, OKX, and MEXC, with real time data from websockets and exchange APIs. The app should let me open multiple panes and windows, link symbols between panes, and save my layout and theme so it comes back the same way next time.

Please include these views, a heatmap for historical order flow, candlesticks, footprint charts, time and sales, DOM or ladder view, and a comparison chart for multiple symbols. The footprint charts should work with live trades and also backfill history when possible. Sound alerts for trades would be great too.

Make it feel polished and modern, with editable colors and a clean dark trading style. If anything needs current API details or docs, look them up online first.
