[Feature request] Make design consistent with libadwaita

[somepaulo]

It would be great to have an option to make the Quick Settings look more like libadwaita: with less border-radius.

Here's the code that does it in gnome-shell.css:

/* Quick Settings */
.quick-settings {
  padding: 12px;
  border-radius: 20px; }
.quick-toggle {
  border-radius: 12px;
  border: none; } /* I want to add borders like on the notifications and calendar popover but it is such a subtle difference I just won't bother with it */
.quick-menu-toggle .quick-toggle-arrow:ltr {
    border-radius: 0 12px 12px 0; }
.quick-menu-toggle .quick-toggle-arrow:rtl {
    border-radius: 12px 0 0 12px; }
.quick-toggle-menu {
  background-color: #353535;
  border-radius: 8px;
  padding: 12px;
  margin: 12px 12px 0; }

A bit late to the party but I've managed to achieve a very similar effect using the Open Bar extension by neuromorph (theming courtesy of the extension as well):

If an implementation is still put into QST, can I ask that it won't interfere with Open Bar? A simple toggle for enabling/disabling border radius options should make sure that the two extensions don't interfere with each other.

Thanks!
