I had purchased the pro version of this add on years ago and just purchased again. I understand the issues the dev was having with people sharing the old link and I definitely like this better and am happy paying twice. This has been such an incredibly useful feature for me because I don't always have access to the internet. Being able to download training videos and educational seminars from youtube to watch when my internet is down has allowed me to accomplish a lot more self improvement than I would have otherwise. Being able to access high resolutions is also helpful for me since I have hearing problems and need to be able to read lips from the speaker (youtube's CC is hit and miss), which is much harder in low quality. This app is incredible and has greatly improved my quality of life. Thank you.
