So far the best theme. Thank you very much.
It doens't break font size and nice level of transparency, all system icons are perfect.
Can you please give a hint to change the "Activities" icon to ArchLinux logo?

Solved. No idea but added something like this.
```
#panel #panelActivities.panel-button > * {


icon-shadow: black 0px 1px 4px;
text-shadow: black 0px 1px 4px;
width: 24px;
height: 24px;
background-color: transparent !important;
background-gradient-direction: none !important;
border: 0 solid transparent !important;
text-shadow: 0 0 transparent !important;
transition-duration: 0ms !important;
box-shadow: none !important;
color: transparent;
/*
background-image: url("common-assets/panel/activities_shadow.png");
*/
background-image: url("gnomeFoot_white.svg");
}

/*
#panel #panelActivities.panel-button:overview:hover {
background: rgba(145,145,145,1);
}*/

#panel #panelActivities.panel-button:overview, #panel #panelActivities.panel-button:focus, #panel #panelActivities.panel-button:checked {
background-color: transparent;
box-shadow: none;
border-bottom-width: 1px;
border-color: transparent;
}
/* overview hänger med på #panel */
#panel #panelActivities.panel-button:focus {
background-color: rgba(175,175,175,.85);
box-shadow: 0 1px 2px rgba(0,0,0,.6);
border-color: rgba(220,220,220,.1);
}
#panel #panelActivities.panel-button:focus > * {
background-image: url("gnomeFoot_solid.svg");
}
#panel.solid #panelActivities.panel-button:focus,
#panel:overview #panelActivities.panel-button:focus {
background-color: rgba(175,175,175,1);
border: none;
box-shadow: none;
}
#panel.solid #panelActivities.panel-button:focus > *,
#panel:overview #panelActivities.panel-button:focus > * {
background-image: url("gnomeFoot_solid.svg");
}
#panel #panelActivities.panel-button:active > *, #panel #panelActivities.panel-button:overview > *, #panel #panelActivities.panel-button:checked > * {
/*
background-image: url("common-assets/panel/activities_shadow.png");
*/
background-image: url("gnomeFoot_white.svg");
}

```

@smekkley thank you very much.
As I wrote in the description here, I am not the author of the original Nova Shell theme. The fact is that the author of this topic abandoned its further development, and I am only an enthusiast who took to correct some of its shortcomings and fix some bugs. Original them is here: https://www.gnome-look.org/p/1013050/
