I have found the app to be nothing more than an expensve shortcut. All this app does is open a new window for YouTube and then there’s this little aggravating thing about it….. if your mouse happens to wander anywhere outside that window, you now have it running in the background. That’s a nice feature but it would be much more convenient if this were a deliberate effort rather than the default. Save your money. You can do the same thing just by creating a bookmark.
