new Vue.$mount is not needed; it also gives warning

[fancydev18]

Please remove

.$mount("#app");

from here

vue-paper-dashboard/src/main.js

Line 14 in 77eeaf1

 }).$mount("#app"); 

as it's not needed. It also gives a warning in console, #app not found.

Also,

render: h => h(App)

isn't needed either.
