Thank you for your great advice.

> they could be sorted by the number of codes in a descending order.

Sorting is important. I will try to implement this.

> There is just too much white color.

I think so too. Now I am trying to implement Dark mode. I will try Material as the solution.

> I see "No title" everywhere, do we need to see "No title" or maybe not show anything?

'No title' is not good as you point out. I'm going to hide it if no title.

I appreciate your advice. I improve front-end more.
