In windows 10 there was an option in taskbar settings to always show all systray icons.
In win11, they made it really annoying so you have to go to settings and add each program separately and whenever the program updates, you have to add it again (so there is perpetually always an arrow with unknown apps hiding underneath which is unsettling.
It would be great to add (always show all) option under taskbar preferences of start11.
