Probably referring to this behavior from TFA:

> Previously you could choose to “never combine” apps so you had one-click access to each document. Now you are required to use two mouse actions to open each.

If you have "foo.txt" and "bar.txt" open in, say, notepad, you get one notepad icon on your taskbar that you click on once to open the list of windows and then once more to actually switch. Previously you could tell windows to never combine the taskbar icons so you'd have two separate icons you could change to in one click.

In windows 10, in a multimonitor setup with "never combined" enabled. If foo.txt is on the left monitor and bar.txt is on the right, the two icons in the taskbar almost always has opposite sort order compared to the the monitor layout.

Clicking the left icon bring up the document on the right monitor and clicking the icon to the right brings up the document on the left. You very often end up picking the wrong document and must do over. That pretty annoying.

Haven't seen this, perhaps because there's a setting in 10 to only show icons on the taskbar where the item is open, which I enable.
