Flavours is a simple Mac program that helps you design and enable stunning themes for your desktop. This app proves to be of great use whenever you get tired of the same default theme and you wish to easily create one that fits your taste.
The application gives you access to a wide range of theme samples shared by other Flavours' users. A good thing is that the app allows you to choose what UI elements from the selected theme should be applied (elements for controls, menu, desktop, etc.).
An advantage of this program is that it offers you plenty of configurations when it comes to designing your own theme. You can select your preferred menu bar styles, icon colors, and much more; and there's also a preview window where you can check the output and decide whether to undo last actions or save the theme.
The only thing I don't like about working with Flavours is the fact that you need to restart your Mac in order to successfully disable a theme.
As for the rest, the program offers me a wide range of stunning themes to choose from and allows me to immediately create my owns. The app is very simple to handle, comes with easy to configure theme editing settings, and doesn't cost much.
