This is what I was really looking for!

Thank you so much for making this amazing app! This is the exact right app that I was looking for.
Im just new to mac OS. I also used to sync folder on Windows 10. And I have come to this app that has the same function. But its a bit shame that free version doesnt have A=>B function. Thats why we have to go pro. Its well developed app. Looks pretty cool enough. And user friendly. I got to know how to use at first.(its really important.) But it could be better if you warn user or help user know how the results of sync is going to be by showing pop-up screen or something.
Anyway, its super cool app to save my time.
