Textools Match Size Tool

Hi Guys,
I’m using blender 2.82 with TexTools addon 1.3.0. I searched the web and came across this Match Size Tool
link for the page : link
But I can’t find this functionality in the latest build. Maybe it was never implemented. My question is that someone knows an addon which do the same? Basically scale the UV-s together (not average them).

Also on the very bottom of this page the TexTools author talk about a debug mode available with Ctr + Alt + D keycombo, but it’s not working. Someone by any chance knows how to enter to this debug mode of textools?
