Is it possible to rearrange icons on the taskbar with StartAllBack?

tested and i kinda like it.  
but when i midclick on a taskbar window it close the window and this is very good. but how to add middle click to 'end task' and not close the window? 

 

found a misterios bug in 3.8.9 with without grouping option. organizing the window of apps and uwp its get fantastic. clicking the uwp app window (putted in the order) the uwp window goes to end moving automaticly to end of row, the order of windows are modified.

That would be 'partially grouping' then. What should happen then if you have two instances and close first one? Would one that left move to combine with pinned one? One pinned one unpinned as is? Move pinned position into new instance?

Where should second instance launch? Alongside first one or at the end?

No, it's not partial grouping.

The expected behavior is that when I launch a task/window using pinned icon on my taskbar it should disappear, or be replaced with task window, just like it is by default in windows.

Currently clicking a pinned icon opens a new window, and I can click it indefinitely for more windows, which is my problem.

The behavior you want opens a can of worms with no good solutions.
