Client activity over 24h

I have a small issue but anoying with the "client activity over 24h" panel.
It take about 1-2 min to load, because we have a lot of client (about 500).

I find a way to remove it in the admin/index.php file, but I have to checkout this file before do a pihole update, and modify again this file.

Is it possible to make all panels customisables ? Hide some of them, move, etc... ?

Thx !

Not yet. But if the request get's enough support we might implement this.
