@ Lomai - thank you very much. Yes, it's something like that
@ Anthony - Thanks to you too. Yes, the themes / visual styles I saw could indeed be used with UxStyle, but as you say, there were some additional customizations that required replacing system files - and I wanted to avoid doing this, because I wasn't sure if I was ready to mess around with my laptop. So, I was looking for something that would be more of a complete package.
Having said that, what happens if I use a theme / visual style with UxStyle but do not do the additional customizations? Would I be right in understanding that, that particular customization won't be present in the new style? Like for e.g the explorer back and forward buttons remaining in the same windows default way?
