So I tried expanding the Taskbar to two rows, but it has problems!
This is what it looks like normally at one row:
Icons are Safely Remove, Bluetooth, Task Manager, Dropbox, Intel Driver Support, HP ToolboxFX, OneDrive, and Windows Security. Icons in a single row are hardware icons and the time.
After going to two rows, it looks like this:
Also, with a 2 row taskbar, the time flickers consistently, even with Seconds turned off (which I would prefer On).
Luckily, going back to a One Row Taskbar actually restores all of the Tray icons.
The snapshots above were after a reboot with 2 Rows on, but I also tried using the Settings Restart Explorer button with the same results.
Guess I'll go back to one row Taskbar, but at least I'll get the Seconds back!
BTW, I was able to pin a .TXT file to the Taskbar following the directions here: How to Pin Almost Anything to the Windows 11 Taskbar. I had done it my original upgrade to Win11 with a PDF and able to move it next to my Acrobat pinned icon. While this worked, I am unable to move it from the very end of the Task Bar! It looks like it wants to, but the horizontal bar indicating its new position is constantly flickering and ultimately it doesn't move.
