gtag is DEPRECATED, not maintained any more ...

See HTAG, it's the descendant : it's basically the same concepts:

• Not tied to guy
• Able to be used in anything which can display html/js/css (pywebview, cefpython3, a browser, .... or guy)
• A lot lot lot better and simpler (better abstractions/code/concepts)
• "intelligent rendering" (redraw only component with states changes)

Migrating components should be easy

GTag is a GUI toolkit for building beautiful applications for mobile, web, and desktop from a single python3 codebase.
