Although the main features that Tube Toolbox offers are related to automation, there are many supplemental features that you will find useful. A few of them are listed below.
The first time that Tube Toolbox runs, it will automatically synchronize your Friends, Subscribers, Favorites and Videos. This allows you quick access to each of these items directly within Tube Toolbox. It is also useful to use these lists when selecting recipients of bulk messages.
Tube Toolbox's interface allows you quick access to all areas of YouTube. Rather than you having to search through YouTube's more complicated menu system, you can simply use Tube Toolbox to get to the different areas of your account.
Tube Toolbox allows you to group your gathered users and videos into groups or lists. You can then send specific messages to certain groups.
Tube Toolbox gives you a complete history of every action you have taken and even allows you to export the data for use in other ways.
