Thank you for your feedback. Nice to hear that you like the downloader.
A UI update is already in planning where I want to make things simpler, reposition some things and for example change the buttons for the formats to a dropdown list instead. At the moment I am working on something else tho, when I am finished with that I will get on work with this again. -NMB
edit- UI got reworked it is still not the best and I will rework it again, but it is a step in the right direction.
