Yeah that part is still bad UX, add mint should prompt something or focus the "add mint" field in the mints tab (right now it just opens the mints tab).

If you know frontend prgramming, feel free to suggest improvements and open a PR! 

 Sorry Im not, but maybe you can disable the button and instead add a hint "scroll down to add a mint"
Because on mobile, I wasnt aware, that I can scroll down and see the options to add a mint...
