We’ll certainly take your feedback along.
Note that iOS and macOS are different. On iOS it is standard to put formatting controls above the soft keyboard. It’s in fact the only place they can go. On Mac, that isn’t standard, because we have no on-screen keyboard. We have opted for menus, which is a pretty standard approach.
Note there is a popover bar. It doesn’t stay active, but maybe that is helpful. It appears when you click the little dot to the left of your text selection.
Note also that this isn’t a case of being stubborn. It is actually quite tricky to figure out where such a bar could go in Agenda. In other note taking apps, the whole window is one note. You put the bar at the top or bottom. In agenda, the notes scroll in a timeline. The bar would probably have to float. Perhaps like the popover we have, but something that can stay permanently visible.
What would you think to something like that? Perhaps we could consider an option to “break off” the popover from the window.
