Feature Request: Log Filtering

Hi,
I'm a new user of WindEdit. Its high performance is very friendly for browsing logs. So would you consider add a log filtering feature. For example, after entering a keyword string, all the lines that contain it are displayed in a new subwindow, and other lines will be hidden in the new subwindow.

No files, tests, or entry points are named. Start by locating WindEdit’s editor and search-related entry points, then clarify the scope of the new subwindow and keyword behavior. Done means matching lines are displayed there while nonmatching lines are hidden.
