If you care about little nuances and tweaks with your Mac but more specifically your Finder. You should look into SideEffects from the HackStore, this little app is still in Beta but it works great and is easy to install. It simply adds color to your sidebar icons. I didn’t think it was a big deal before I tried it, after installing and seeing the beautiful cool icons it just makes looking at my Finder a little more enjoyable. If you don’t see any change just click the relaunch Finder icon and that should fix it. Check it out and let us know what you think?
