Amazing, Beautiful, Perfect

It's harder to find good extensions for Safari than for Chrome, but after recent revelations regarding google's data usage, I switched - and I felt like I was going to be stuck with "boomer internet." Not after Tampermonkey! I'm only ok at coding, but I'm able to find scripts that are incredibly useful, and install them in seconds. Obviously give everything a once-over before installing, but Tampermonkey will save you so much time and effort!

Hope the icon can be refined

The icons in both toolbar and launchpad look weird, compared with other icons from other apps.
