currently using the macOS Big Sur Beta and was styling Alfred for the upcoming makeover of the macOS UI. I prefer a look as close to the system UI as possible.

A little unfortunate, that there is no option to round the corners on the selection background elements, they appear very pointy in the new environment of even more rounded corners in macOS Big Sur.
