I love the overall clean aesthetic of Agenda, but it’s difficult to know how I can drag my window around (and where to position my mouse cursor to do so) if I need to rearrange my screen. It usually takes me a few tries to figure out.
Yeah, the main difficulty I have is that there isn’t anything to visually indicate (even temporarily) the area where I should place my mouse (or even if I’m in the right place). The app in general doesn’t have a traditional title bar area, so it’s hard to distinguish the area you highlighted above with the rest of the app.
As a visual reference you can stick with anything north of the Project title in the center pane.
