the new Synchronize-It looks much like Compare-It. Many users may like the more colorful, friendly look, but I am one of those guys who like it simple. So I want to make a suggestion: why not offer an option in both apps to dislplay all buttons/icons grayscaled?
I'm afraid grayscale icons could be confusing due to disabled state similarity. I'm planning to add option to use another icons style - like it was in version 2. But I will check how it will look in gray-scale too, thank you for suggestion.
