It's quite accessible and easy to use, since you just need to enter your search query into Minitube, and choose the video you want to watch, which the program will add to the end of your playlist.
Minitube includes the same functions you would find on a classic media player, with pause, skip video, and volume control, as well as options to directly share the video on your social network. You can also select the quality of each video.
Forget all those annoying messages reminding you that you have to install Flash when you want to watch a video on YouTube. Instead, use Minitube to access all of them.
