Congrats to Clem, and all Mint team for your hard work. I am from Croatia, and user of linux Mint for long time now, and noticed great UI improvements (NEMO,CINNAMON) just since version 13!. Today i made some icon changes with sidebar on your nemo picture:D believing they are better visible in light color. And one thing if i may suggest..elementary mint icons to be little more professional..for example..fewer colors and more geometric like (music, pictures,downloads,documents) have graphical symbol on it..those symbols, if they were all in black or monochrome style, it woud give a more pro touch to them..Cheers to you all
Hope something will happen of this.
