PyTube is an opensource software which allows you to easier search, manage and convert your YouTube videos. Installing PyTube is very simple; for example, on Ubuntu you can directly add this software using the Synaptic Package Manager and marking it for installation from the menu (as usual, using the Search field you will reduce your searching time). The graphical interface is very simple and all the features can be intuitively understood. Using the search bar you are able to find all the related videos very rapidly, and you can select just the videos you desire to download. PyTube has also many interesting "minor" features like merge-rotate-resize video or -generate a ringtone- contained in the "Multimedia Tool" menu. Moreover PyTube is able to convert them to avi, in just a click. I found this software very useful to improve my Ubuntu knowledge and I recommend to all the people who need a flexible software to deeply navigate YouTube. Recommended!
