I think the context menu of compareIt! is very handy. Would it be possible to do a similar thing for synchronize it? So that by right clicking a folder, you would get options like "set source folder", "set target folder". That'd be very convenient!
Thank you very much for the new double update, that's awesome!
When you keep working on synchronizeIt, please also consider this context feature. Since you already have it in compareIt!, I suppose you already know how to do it. It would be extremely handy!
