Future Updates and feedback for Mithqal Calculator V2

Allah'u'Abhá everyone! Graduating soon (from uni) and will start to work on lots of updates for the Mithqal Calculator (on my free time) (link to OG post Here).
Updates for V2 include:

1. add an about page. In the about page, will be what the site is, why, a 'buy me a coffee' button (or pateron for more support?), and a 'request a feature/report a bug' button. Explaining (and linking) where the metal rates are from.
2. changing the name (of repo and title) to just 'Mithqal Calculator' (the pun is nice, but just causes confusion.... ;(
3. add country flag icon, full currency name, and currency abbreviation to dropdown (thanks  for the tip!)
4. Add a 'save to homescreen' button (either automating the process of making the website into a homescreen app on your phone, or showing a tutorial how) (or maybe just make an app for phones?)
5. Add a stats page (showing live stats of how many people used the calculator, and making an estimate of how much time has been saved
6. adding a Huqúqu'lláh quote (random by a bahai quote api repo) to the main page.
7. Make the intractable fields more obvious (make them move a bit if haven't been touched, or glow... any ideas? I like this sentence structure design.

If there is anything else or any other app or website ideas you think is needed that can somewhat be of service to humanity, please let me know! I love learning and want to practice coding!
