Personal Documents Organiser for Windows in C#

New version available: Download Documents Order Obsession v. 0.2.0.0
Lately I have started to work on some projects on C# and I am really excited about the way that C# applications communicate with Windows.
Documents Order Obsession v. 0.1.0.0 is an application that will help you to organise your documents and put them in order. However, it can be used to track and organise any kind of information as the given categories can be configured from the user.
Some of its features are:
+ Create up to six categories to add your document entries
+ Color each category to be easier to distinct entries belonging to a specific category
+ Show/Hide completed tasks
+ Filter categories
+ Keep History of creating, editing and deleting entries (History can be disabled)
+ Import/Export the entries from/to a XML file
+ View Statistics
Documents Order Obsession v. 0.1.0.0 is written in C# and requires Microsoft .NET Framework 4 (x86 and x64), SQL Server Compact 3.5 SP2 and Windows Installer 3.1 to be installed. If you do not have them installed do not worry. The installer will download all the prerequisites from Microsoft.
To install:
1. Download Documents Order Obsession v. 0.1.0.0
