* Centering of <thead> in device summary table
I add the property "text-align: center;" to class ".gridster *"
* Adding lines in app.css
I add these two lines to the style sheet:
.select2-dropdown:is(.tw-dark *) {background-color: #2E3338;}
.select2-results__group:is(.tw-dark *) {border: 1px solid #1f2225;}
