It is a source of daily/hourly frustration that clicking on the icon portion of a layer will open it while the only way to open an artboard is to double click the icon (just to mention one). This is only one such inconsistency, but it's very frustrating to have layers expand when I'm only trying to select it as the first of a multiple selection while at the same time, clicking anywhere on an artboard from the list will only select it. In this latter case, one has to both double-click and do so in a small hitbox.
