Can you make a screenshot of how it looks with and without the tweaker?

Also, can you try the arranging options with all of the tweaks off (but with the tweaker runnign)?

If the arranging options work correctly with the tweaks turned off, please try to isolate the problematic tweak by enabling them one at a time.

Actually, it helped me focus less on testing and more on fixing. So all three issues should be fixed in the newly released alpha version :)

See the following blog post for the update progress:

That was already reported here:

Please try the beta version, which has a fix for the issue.

Actually, 7+ Taskbar Tweaker v4.1 indeed sets the volume control program to run in higher priority, so that it will launch faster. There's no reason to set the tweaker itself to run in high priority, since most functionality actually runs from within explorer.

Closing. If the topic author had something else in mind: feel free to leave a comment.

While not directly possible, it can be done with a combination of this feature:

And the NirCmd command line tool:

That is not trivial to implement, and is not planned at this time.

I don't think that 7+ Taskbar Tweaker can have such a feature - it's difficult to cooperate with an unknown virtual desktop software correctly. You can try using the 7+ Taskbar Tweaking Library to accomplish item reordering on the taskbar without having to hide or show the actual windows.

Other notes:

• There's a virtual desktop utility of mine, Virtuoz, which provides simple virtual desktop management for Windows 7 and 8, while preserving taskbar order.
• Windows 10 has a built-in virtual desktop functionality, and 7+ Taskbar Tweaker has an option to keep the taskbar order while using it.
• I might have a piece of code lying somewhere which can save and restore the taskbar items order. Let me know if it can help, and I'll check if I can find it.
