I have only one request:
Is it possible to add option for automatic favicon choosing for Non-Iconized Tab from predefined set of favicons?
The number of Non-Iconized sites grows and sometimes almost all tabs become Non-Iconized.
In such case is highly desired to "connect" different favicons to such sites.
The algorythm can be very simple.
Let assume we have K alternatives for favicons.
We can get the sum of all characters of site host, let say, S and S by module K (S % K) will give us one of K favicons and it will be connected to this site.
Thank you
