For some reason the app supports a separate standalone window mode as well [0]. It's not clear why the developer took the trouble to support two different modes when the menubar mode doesn't seem to add anything (like a live-updating icon for throughput).

Well, I can think of one reason why it wasn't that much more trouble. François Chollet had a nice tweet [1] on why removing human cognitive friction is resulting in needless software complexity.

Are you saying you wish this was a desktop app and you would just open it occasionally when curious?

If so, it feels like a needlessly indirect and combative way to go about it.
