It used to be that the icon used for konqueror in the taskbar was the favicon of the web site. We could have many konqueror windows open and one could easily differentiate between them by looking at the favicon.
Now, there is a regression by the fact that all konqueror windows show the konqueror icon in the taskbar.
This useful feature should be back, probably as an option for those who don't like it this way.
Why do you confirm your own bugs, if you did not check the code?
