Thanks für your suggestion. I'll let you know if I find something.

Unfortunately, no windows programming skills. I'm still hoping for a future version of your utility. And thanks for your feedback!

Yeah, that's definitely better than nothing. But automatic sorting would be even better :-). I'd probably be too lazy after a while to open the Taskbar Inspector and re-sort the entries. Or is there a way to execute that from a shell script or make it a simple operation?
