Images in Thumbnail and taskbar options

Sometime we named folders to remember where we keep our data but we always see thumbnails before open the folder to check what is in it where so many folder we have. And the taskbar in window 10 was good but here in window 11 the taskbar has only Taskbar setting, we cannot kill task to go to taskbar with right click. so i think these simple option should be in next update. Thank you
