Pinned tabs are very useful feature in Safari and I'm using it all the time.
But, I'm having some experience problem with it.
When I pin several tabs from the same domain but different subdomains, I'm getting the first letter as the icon of this pinned tab to be exactly the same. Then it takes me a while to find the tab I was looking for by switching through them one by one.
Is it possible to manually change the icon for these tabs or at least make it to use the first letter of the subdomain instead of the domain name, so it will be much faster accessible?
