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.

> removing human cognitive friction is resulting in needless software complexity
This is kind of a hilarious statement just on the surface. Isn't removing burden from humans the whole purpose of software? How can you call the complexity "needless"?!
(the actual tweet seems to go into a bit more detail around being incentivized to find good abstractions)
I think you're conflating the burden of creation with the burden of relevance, suitability, usability and usefulness of the created artifact. The more the person in charge is disengaged, the sloppier the output is likely to be.
