Please use native toolkits. At least Gtk or Qt :)

Flash is just “We don’t like to pay developers. We prefer you to pay more for memory. And your processor. And by the why, we don’t care about your security.”

Ironically memory prices are skyrocketing right now. Even the best known Electron application (Signal) is eating memory like it is free. Similiar native applications integrate much better and use a fraction of memory (e.g. Fractal).

PS: If autonomous locally usage doesn’t make sense a mere web-app is good way. At least it is then a single tab in the web-browser and most platforms are covered (if you don’t target Chrome exclusively…). In this case possible step? At least not 500 MB wasted.
