Tutorial of "class" to modify

[tistoubapt]

Hello

Has anyone made a tutorial with most of the things that need to be modified ?
Image of Windows, and the reference to the modification to be made in the soft, for example
As was done with WSB a long time ago (for W7) : https://sharewithhaviz-data.blogspot.com/2010/12/modif-tampilan-win7-step-by-step-buatan.html

In WSB, it was more "intuitive" to find, but the software was paid, you can't have everything

I'm looking for how to change the margin of the taskbar thumbnails, for example, and I can't find it

Thanks

PS : And again a big thanks to the developer for his soft
