Support was added in v5.10.

I might be able to implement that. When that happens, if you close and re-launch the tweaker, does the taskbar become narrow again?

Perhaps you have v5.9.1.6 cached, try downloading form an incognito window.

Please try the newly released v5.9.1.7 beta.

Thanks, I guess :)

Yes, build 19042.608 is still unsupported. v5.9.1.6 only fixes combability with update KB4580386 of Windows 10 version 1909. I'll look into build 19042.608 in the near future.
