Adjust UI size?

In the Windows version, you can customize how big your color swatches are and the general UI of the workspace. Is this not available in the Mac version? Because the color swatches and icons pertaining to things in your design in the inspectors is REALLY small. Probably because of the high resolution of an iMac Retina display? I shouldn't have to lower my display resolution to edit UI size.

Can this be done, or can the ability be added? Anyone with not the greatest eye sight would struggle with this UI.
