Tired of watching sloppy video playback from YouTube? I was, and it got me pretty exited when I came across this project called minitube.
It’s basically a browser for YouTube, you can search content (of course), add playlists, share videos to your Twitter/Facebook account but also via e-mail. But best of all, it can float on top of your screen so you can do some productive work while watching your favorites:) Pretty awesome when you want to follow a tutorial or just general multitasking. The app runs on Linux (GTK), OS X & Windows. The user interface is clean and simple, no clutter;)
One of the other things I found which is a huge plus and worth to mention is that the playback is flawless! And this has never been the case for me.
