I liked the Windows vertical taskbar.

It kept the positions of the applications and I could rearrange them as well.

When Windows 11 removed the vertical taskbar, it really broke my way of working.

I keep many applications, documents, Excel, PowerPoint etc. open and keep them for days.

Not all of them are needed all the time but there are groups that I need, maybe six for half the day, something else later, but I don’t close them, because I might need them again.

Now this behavior is a problem when you don’t have a way to put them aside. Every Alt+Tab, Win+Tab or click on the taskbar, you have to deal with that clutter.

This problem in Win 11 is really visible in a Teams meeting. Almost everyone who is sharing their screen and trying to switch between apps gets confused and opens the wrong windows or loses context.

Spatial Taskbar solves that problem. All it does is put the apps in a stack and optionally allows you to put them in sections if you need more organization than that. As I kept using it, I added a few more features, but they are all optional. The key point is that simple stack of window handles which keep their place and allow you to move them around.

Also it does not hog space on the screen. Alt+Space brings it on, and Alt+Space again to turn it off or just click away.
