Tracking Changes Bar
BCGControlBar Pro (MFC)

BCGControlBar for .NET
The advanced edit control can display a special bar that indicates the changes on the left side. The developer can easily turn on/off the tracking changes bar and customize this column's appearance. This feature allows you to observe your changes and makes the navigation inside the edit control easier.
Sample code:
// Enable tracking changes:
m_wndEdit.EnableTrackChanges();
