Very great calculator, good design, but it has too many functions. I advise you to add a "search" to find points, I also personally like the intuitive interfaces that are easy to understand even for beginners newbie.
Therefore, it may be necessary to add documentation.
In conclusion, the project is not bad, but I wanted the interface to be more user-friendly for beginners.
Thanks so much for the feedback! I'll definitely add a search bar in the future. I think the best UI's don't need documentation. Not saying mine is the best, but if you feel like I need documentation then I'm doing something wrong.
Yes bro, maybe I just misunderstood the interface a little, it's still great, but I wanted a simpler interface, it will attract more community to the site because it will be easier for people to understand what and how.
I hope your project turns out great and the community loves it.
