I notice for popup windows you display the favicon for the window in the taskbar. If would be a great feature if you could also do this for the main browser window - I've been looking for a way to do this via the browser for years.

In the screenshot Display Fusion is using the favicon for the taskbar button which I really like - I'd love it if the taskbar button for a broswer was always the favicon of the selected tab. I use a lot of browser based tools in multiple windows and it can be hard to find the right window when all the browser taskbar icons are the same. The tools I used spawn a lot of windows adding to the confusion - I actually use DisplayFusion triggers to close spawned windows to reduce clutter. A while ago I had a hard look to see if there was a browser/plugin out there that put favicon in the taskbar and did this and couldn't find anything.

What would be even more amazing would if a trigger could determine the DisplayFusion taskbar icon based on the window title or browser URL. Taking my screenshot as an example I would use that to have a different icon for the main window and the Tracer window. If the trigger could do a regex match on the URL of the window it would be useful for distinguishing between dev and prod servers for developers.
