How can the icons of pinned tabs in Safari be changed?
With the latest OS X El Capitan, there's the possibility to pin tabs to the left side of the tab bar and I love this little function.
Unfortunately one tab shows a wrong letter. The site I've pinned is a ticket system I have to use at my work called OTRS. However, the letter the pinned tab shows is an U and that irritates me every time I use this tab.
The other ones I use are okay. So I thought that I could simply change the icon bit I haven't found any possibility.
Do anyone know how this is possible? I fear that there's not such a implementation...
