Everything can be done. The question is, how much effort is required for it.

Currently, I don't plan to implement it, sorry.

I do not have 7+TT set to run on startup.

That's why it stops working, probably. The settings don't apply when the tweaker isn't running.

This is a known issue, which happens without the tweaker, too. The order of the taskbar items gets reset every time a virtual desktop is being switched on Windows 10.

That's not a bug, that's how it works, with or without the tweaker. Changing from bug to idea.

If the issue persists after uninstalling the tweaker, the tweaker has nothing to do with the issue.

7+ Taskbar Tweaker doesn't do permanent changes to the system.

The option is not supported in Windows 10.

It's not about the builds being stable in the sense of having, or not having, problems.

The tweaker (mis)uses the internal representations of variables and structures in explorer. These representations usually don't change between stable versions, but they change often in experimental builds. Thus, if I decide to support the insider builds, there would have to be a different tweaker version for every build.

Fast Ring builds are not supported. More information:
