@jprosadoDE in March, we changed the Safari extension from an app extension to a web extension - which was a large fundamental change in how it works and is displayed within the browser.
Part of that change was the UI (the badge color, and window size) are controlled by the available Web Extension APIs.
We have the feedback captured on the height, but there is a webkit issue that is causing us to be limited to a 440px “square” popup at the moment. Hopefully we’ll be unblocked soon
