I use only fullHD. I can decrease scale of page, but all text becomes unreadable and problem not fully solved. Main troubles in additional panel, which placed OVER 3D-area, so needs place it BELOW of preview area.
Perhaps the "Problem areas" widget could be contained in a box underneath (and no wider than) the "show heatmap view" label, with the buttons closer together and arranged in multiple rows of four or five each ?
