rdblclick for taskbaritem:

I've improved the handling of double clicks, which is a tricky part.

I believe it should work correctly for your use case.

As for the rdblclick for emptyspace:

The taskbar doesn't receive the appropriate message (WM_RBUTTONDBLCLK), even though it can be seen in Spy++.

I assume the right click menu makes the system process the message. I'm not sure whether, and how, it can be solved.

Update: by disabling the right click menu, the tasbkar receives the message, which supports my assumption.

About the X1/X2 buttons: this was indeed a bug.

It will be fixed in the next version.

I looked at the issue, and there's a fundamental problem with it:

I've managed to overcome the limitation, but the issue is that the width restores back to explorer's minimum upon system restart. The thing is that explorer starts before the tweaker on system startup, so the tweaker can't prevent from explorer from resetting the width.

I don't understand what the suggestion is about.

If it's still relevant, please create a new suggestion.

If possible, include a screenshot to make it easier to understand.
